How do I do multiple time signatures?

How do I have different parts in different time signatures, where the length of the measures is the same for both parts, as in this example:

Hi ThatViolaGuy.
You’ll have to use the technique involving local time signatures and hidden tuplets. There’s an (old) article at Scoring notes that describe this thoroughly

In this case, I would make repeated use of pickup-bars and hidden tuplets to achieve the result
