Is it possible to iterate through a collection multi-select picklist values on a single record using a flow loop element?

Flow

Ok, this should be simple but I just can't figure it out. 

1. I have a multi-select picklist that lists out all active users. Easily accomplished via a dynamic choice that retrieves the user name and ID.
2. I need to pass the selected user names to a variable collection so I can lookup their ID. 
   1. I realize that this ID already exists in my dynamic choice but I can't figure out how to get the picklist to return that value instead. If this can be done please let me know. 
3. Lookup ID using Name. 
4. I then use this ID for creation of multiple records on multiple objects. 

I cannot figure out how to get the selected "Screen Multi-Select Fields" values to pass into a collection. 

Can anyone help me with this?
