As a Roblox developer, it is currently impossible to change the rank in a group of multiple users in a bulk.
If Roblox is able to address this issue, it would improve my group experience because it makes the management of (big) groups alot easier.
It would look like this:
This is just a simple edited screenshot using Paint, don’t mind the bad edit.
There would be checkable boxes right above the head thumbnail of every member. When you selected a group of users, you can just change the rank of one selected user and change the rank. When you did that, the rank will be changed of all selected users to the chosen role.
A case where this should be used is when you manage a group which has virtual jobs. After a training or interview sesion, you will be able to rank everyone who passed to their new rank.
I am curious about what you think about this and I love to hear additions or changes to this feature request!
