I think if you can solve it technical, it can be of good use. I am not sure how many others would use this feature when it is there. I am sure some people will not mind having this feature.
And I am very certain that it can be implemented not that difficult. Worst case with a text file saving the number, but you already have the files in a temporary directory where you only need to count. Moreover, the real name in the background and the visible one don't need to be identically. -- <https://forum.pspad.com/read.php?2,53682,73727> PSPad freeware editor https://www.pspad.com
