Synchronizing text content across mockups (e.g. desktop and mobile)

Hey everyone!

We have a lot of mockups with exactly the same text across desktop + mobile. I’m tweaking text in desktop mockups and manually copy-pasting it to mobile versions, which is tedious and error-prone.

Is there a way (e.g. through a plugin) to link two or more text boxes so that when I edit one, the text changes are automatically synchronized to the other?

Thanks for any help!
