Link Store to User Profile

I am getting a bit frustrated with the “Stores” taxonomy that is quite important in getting comparisons right.

I am having to:
1. Create a user
2. Create a store for that user
3. Manually link every listing created by a user to his manually created store.

There must be a better way to do this. Can a store not be created automatically when I create a user (user&store names are exactly the same) and have all listings assigned automatically?
