Yeah, sure, but you don't need a dedicated plan mode for that at all. you can just do it in auto mode, and say "let's do some planning first", and Claude will (nowadays) be smart enough to understand that it's not supposed to jump straight into the implementation.
So again: You don't need plan mode, auto mode works just fine, there is no difference in the workflows here.
