Add ability to add/modify SMB users

Is your feature request related to a problem? Please describe. It's not really a "problem", but more of a necessary feature. There isn't a way to add users to access a SMB share.

Describe the solution you'd like Currently, there is no way to add a user for SMB access to a shared folder. I would like some way to do this in the GUI rather than manually in the console. It doesn't have to be an extensive permissions GUI but something to just simply add/modify users for access to shared folders would be nice.

Describe alternatives you've considered
