Add max limit on dropdown within a form for conference planning

Being able to apply a max limit for how many times users may select an item from a drop-down would enable:

  1. Conference planners to avoid oversubscription to events or breakouts that are happening simultaneously.
  2. Another use-case is for room booking and venue capacity.

For example:
Drop-down option A (max 40)
Drop-down option B (max 20)
Drop-down option C (max 50)

Once it is maxed the drop-down option should not be selectable and indicate session full.

On Jotform app this is possible via a quantified gift registry…which is another use case I imagine.
