Include o365 Group Web Url in the json of https://graph.microsoft.com/v1.0/groups/

I love all the information that the /groups returns for me. I use it to provide my users with quick access to their Groups. Unfortunately it does not return the actual site url for the Group. You can get that by doing something like https://graph.microsoft.com/v1.0/groups/{id}/sites/root but there are two problems with that

1 - You have to run this for each individual group - a lot of unnecessary chatter

2 - If the Group is private and I am not a member I get Access Denied

Can you add that into the json returned for the basic Groups query? 

thanks
