[Hustle] Hustle slide-in trigger

Howdy.

Adam has already answered this question and said it is not currently possible, but I'd like to know if there is a way you can actually have the Hustle slide-in trigger initially on a timed interval and then once it is closed, be able to re-open it with a button?

Example page is here:

Cheers,
