Is there a way to create an Image Rename Mask for the Image Rename Add-on that renames images to a specific file name as it loops through a list of image uploads?

I have accomplished this using a filename in a hidden field, but as the Image Rename loops through my image uploads (1 to 10) it only sees the first hidden fields. As a result it uses the hidden field for the first name and then adds a suffix like "_1" or "_2" to the remaining file names.

I would like to tell it exactly what file name to use for every file. Something like Photo1, Photo2, Photo3 for example.

Can this be done?

Thx,
Mark
