Fix the process for renaming support groups

We have a variety of teams using Zendesk which sometimes means renaming groups. This causes significant problems in Explore:

• Renaming the group looks seamless in support, but in Explore it seems to actually create a new group
• All reports based on the renamed group stop working as soon as the change is synced to Explore
• There is no way to identify which reports might be using the group 
• Explore doesn't have any options to bulk edit, replace, save a search or even open a query in a new tab so for every report I need to search, open the query, edit it and then repeat. Based on the search I just did I need to update 253 reports as a result of renaming a group, which is going to require a lot of manual effort
