Designing multibody sheet metal parts offers many possibilities, but it also has some limitations.

For example, a part made as one object intended to be cut.

If I mark cut perpendicular – objects disappear, remaining only one. Geometry optimization it doesn't matter here.

If we turn it off cut perpendicular – you can leave them all (four here) objects. But… they are not cut perpendicularly.

Therefore, in a separate operation, I perform the operation cut perpendicular so many times, how many sheets were created. Groups do not work with multibody parts.
