Rclone cleanup specify options

I'm using B2 and I'm trying to migrate off the official "b2" cli tool. One thing which I'm still using it for is

b2 cancel_all_unfinished_large_files

As I understand this has been implemented in rclone here: b2: cleanup unfinished large files by garrmcnu · Pull Request #2810 · rclone/rclone · GitHub

My problem is that this removes all the old versions, which would be disastrous for my archiving purposes. I'd simply need to remove the leftover unfinished large files, I definitely do not want to touch the versions.

AFAIK, this is not possible today with rclone. Can you add an option or a command or similar to do this?
