Allow Group Admin to customise their Join Group Membership link

Hi Tuan, on my wishlist would be the option for group admins to be able to customise their Group Membership link.  At the moment if requested I do this for them manually by going into the database.  Generally they want something to do with their business name and it would be great if they could make the change themselves via a module on their account page.

Taking it a step further, if we also had a QR generator so they could click to create a QR code for their join group membership link (which I also do manually for them) they would then be almost self sufficient

Thanks for your consideration
Tracey
