I was wandering if there would be somehow a way to limit the bump up and highlights usage hourly? For example I would like to have a listing package for paid accounts (for example properties) that contains 2 bump ups and those users can use them at any time but for free accounts the bump ups and highlights can be used every X hours being that X available to configure. So that, when I create the package I offer 2 bump up or highlights with a limit use of 12 hours in between, if the user uses a highlight, he or she cannot highlight or bump up the same listing until 12 hours has past but should be able to use it for a different listing.

I hope I'm clear on my concern.
