Do you mean add the custom format to rename file to include resource index number?
Yes, right now the only way to have each download with a unique filename is to include the ORIGINAL_NAME or ORIGINAL_NAME_FIRST custom formats, but that can give you a very long filename some times, and those are also not related to the order of pics/videos in a post.
Would it be possible to add a Custom Format to the list to add the index of the specific media to be downloaded (in post URL it's the value in "?img_index=")? It would be very useful to download multiple media from the same post and having the names ending with _1, _2 and so on.
