File Uploads: Rename uploaded file with data on form fields.

My users upload jpgs. Based on their data-entry in other fields, I want to automatically rename the upload...

Original filename being upload:  abc.jpg

For example, 4 fields:

  Field: ImageCategory   Value: P
  Field: ImageTitle          Value: A Pretty Picture
  Field: FirstName           Value: Bill
  Field: LastName           Value: Smith

On submit, the uploading file is saved as:

      P_A Pretty Picture_Bill Smith.jpg

I manually add the underscore symbols, spaces, and ".jpg"

It this possible?

This is not currently possible to do, but I will open a feature request on our second level, although we cannot provide an ETA, we will keep you updated via this thread.
