Split tweets - option to set number of tweets per image from a thread

For longer threads (multi-tweet posts) it would be nice to have an option to specify how many tweets to include per image. Right now the “Split Tweets” feature does 1 tweet per image. Depending on the amount of text per tweet it would be valuable to be able to select 2-3 tweets per image as presently to do this kind of consolidation you have to merge the individual split tweets together or copy and split manually a larger 1 image non-split thread.
