It seems like grouping feature lacks of some basic features. We have over 350 sites and we want to create a map for every one of them. Problem is group details page cannot be changed for every site we have. It continuously shows the same page. There are some annoying workarounds but none of them completely fits our situation.
Some folks point out the same problem they have.
Custom Property request
So, If you want us to use grouping functionality. Please include these features in the next release!
I've marked this for PM to review.
Thanks for the feedback.
