[Feature request] Add/assign apps to multiple users at the same time #906

Hello,

I googled for this and ended up editing the sqlite directly, but I may have missed something simple.

It would be great to be able to assign apps to multiple users when adding, or when editing.

The use case is say adding a recipe app to multiple users, at the moment it is necessary to go and add it to each user individually.

Would also be useful to have shared tags.

Thanks for making Heimdall, it is great!
