Repeating take scope should not be idempotent

[AndreasArvidsson]

Taking the same scope again really makes no sense. It would be nice if we could utilize repetition to extend selection.

take round twice == take grand round take token twice == take two tokens

This could probably implemented on the set selection action. Maybe using a final stage?
