Wildcard In File Monitor

In our setup we used ftproot\%USER% for the path at which File Monitor would look and clean up files based on age. When it was not working, I opened a support request and learned that the File Monitor cannot use wildcards. I believe that one of two things needs to happen:

1. Either File Monitor should support wildcards like the one above, or...
2. The File Monitor should not let you save it with wildcards if they are not supported.

Thanks!
