Easier interaction when changing an agent's default group

Please give a quick overview of your product feature request or feedback and note who in your org is affected by this issue [ex. agents, admins, customers, etc.]. (2-3 sentences)

Editing an agent's groups through their profile can be unnecessarily tedious, especially if you have a large number of groups. This is because the "default group" dropdown is listed after all the group cards. Depending on your processes, making simple changes to an agent's groups can be a frequent annoyance or a rare head-scratcher for admins (or agents with the newly-introduced permission to modify group memberships).

What problem do you see this solving? (1-2 sentences) 

Changing an agent's groups often involves adding a user to a new group, setting that group to be their default group, and removing them from their previous group. Since changing the default group must occur after setting the new group but before removing the old one, this involves at least scrolling to the bottom of the modal to change the default group before scrolling back up to remove their old group. It can be easy to lose your place, and especially frustrating if the new/old groups are close to each other but far from the bottom.

When was the last time you were affected by this lack of functionality, or specific tool? What happened? How often does this problem occur and how does this impact your business? (3-4 sentences)

It's a minor annoyance that I believe would require an appropriately minor effort to fix. I recently had to migrate a set of agents to a new group, which required scrolling up and down the group modal for about 5x as long as I believe is necessary. This happens a few times each month in my current environment, but has been a near-daily task in the past.

Are you currently using a workaround to solve this problem? (If yes, please explain) (1-2 sentences)

I have considered writing a custom app to make group changes easier, but it's not currently annoying/frequent enough to spend hours fixing.

What would be your ideal solution to this problem? How would it work or function? (1-2 sentences)

I can imagine two changes that would greatly improve this process. The first is some UI element on the group card itself that allows you to set it as the default group directly, which would also help to indicate which group is an agent's default. The second change would be to replace the "you can't remove this group unless you set another as default" message with a prompt that allows you to immediately select a new default group, perhaps surfacing the exact dropdown that you'd otherwise need to scroll to.

Current: Scroll to new group, click it. Scroll to bottom, make default dropdown selection. Scroll back up, remove former group.

Potential: Scroll to new group, click it. Click "make default" button on the same card. Scroll to old group, click to remove. Done.

Or: Scroll to old default group, click it. Select new default group from the dropdown. Done.
