Restrict "Date added behavior for new content" to video/audio content only

[rs232]

Might I suggest for the "Date added behaviour for new content" option to restrict the scope to the date of videos (or audio) only?
I have recently started to use TinyMediaManager to create .nfo in the movie folders, to my surprise a given new file in the folder, despite this not being a video one, brought the movie to the top of the list. This ap[plies to subtitles, images, nfo, etc. In my specific case this is unwanted and would prefer for the data of the mp4/mkv/etc to be look at only.

Thanks
