Renaming file in Lightroom

I have seen many people complaining of the lack of possibility to (automatically) renaming a file after Topaz has adjusted the file. For example, it would be very handy to know, from the filename, whether it has been adjusted with Topaz Picture AI for example.

Please point to all the people who complain of the lack of renaming. Remember that LR would become confused because the image is NOT there. You would have to sync the folder to reimport it the LR so all links would be lost.

I believe the EXIF holding the name of the adjusting app would be better.
