Rename file before upload to plex-cloud

there is a script to rename files based on the current Association plex?
I have several files that are numbers and always carried a manual association with plex
now that I would try plex-cloud should do manual rename the files, I was looking for a way to automate? any suggestions?

FileBot it’s not able to rename my file, I’ve already tried.

Movie file name it’s really:

0001.mkv
0002.mkv
0003.avi

i have only in plex association filename->Title
