This is more or less a Known Issue atm.
There is still some functionality missing in regards to UDIM, we have a task open for this, see blender/blender#72390 (Improve UDIM functionality), "Support for UDIMs in various other features that work with images"

Will add this report there as well.

Thanks, but for this task we want to update the existing operator in Blender to support UDIMs, not switch to a different add-on or user interface.

I think the operator could automatically detect when there are UDIMs and not require UDIM start, end, grid size to be specified manually by the user.

Yes it would be great if operator can handle this however I'm not enough experienced to do this ;)

I think it would make sense if you have to add a substitution token like .. or .. as we already have in the workflow. An error could come up if you don't have this token (like there also already is in the other part of the workflow).
