Whilst "not supported" you could write your own custom equivalent. You could add a button, which triggers a saveInto() which stashes whatever data you define into a variable. Depending on where you want to "paste" that data you may stash it in a local! variable or a ri! variable, the latter of which can be mapped to a pv! and thus made re-usable in process, or even stored to a database table and retrievable anywhere else in your application.
