Limit Form Entries with condition by specific selected options

Hello, I found this post very helpful but it is closed now so couldn't ask in that thread: http://www.gravityhelp.com/forums/topic/display-number-of-form-entries-left-per-form

I am looking to show the # of entries available but with a condition. My client is using their form to track registrations for a class. They have 1 class that is pre-scheduled for about 5 dates. I was wondering if its possible to limit the entries of the form based off of the date the user picks from the drop down menu.

Example: Every date has 30 entries allowed. But each date should have its own unique count of allotted entries. So date 1 could have 10 left but date 2 & 3 could still have 25 left.

Any tips on this would be great!

Thanks!
