File restrictions

We have a very simple interface with a client using the Active transfer web-client for simple csv upload.

I understand that using MWS I can add restrictions to this users account such as.

  1. File Name Filters (Patterns)
    Here i can stop the user from uploading files based on the extension
    eg .exe, .xlsx etc

  2. I can also restrict this users access to folders by using the
    Block Paths Matching These Patterns option

My question is , how to implement :
"This user can only upload files that match this pattern for example “TestingApp.csv’”.
so basically if the user tries to upload anything else an error is shown on the webclient (similar to the error he would get if he tried to upload a .exe file.)

Thanks
