@Creative2 many thanks for sharing your suggestions and with us, and welcome to the Elfsight Community! 
You know, I love your idea about subgroups, I guess it could be a great addition to the plugin! I really hope our devs will be able to consider it for the future updates. I’ll keep you updated on the progress here 
As for your second idea, it seems we already have a similar request, so you’re very welcome to vote for it and add your ideas if any here. We try to open a separate topic for each idea so that it’s more clear
Thanks a lot for your help, it’s truly appreciated!
