Hey Seth,
Thanks for the post. Definitely interested to hear if anyone else has a solution for this right now. We have discussed adding a timer to the display screen internally and it's something we would love to potentially offer one day in the future.
In the meantime, I found this feature request on our official feature requests page. If you could upvote it as well as add anything additional to the conversation it will help us when considering adding this feature to future updates.
Thanks again for bringing this up and if you have any other feature requests feel free to submit them here
