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
