Custom Field (max selection) - interested?

Hello,

I'm wondering if anyone would find this of value. Let's say you have a custom field within the registration of an event for different time slots for an event. Would anyone find it useful to have a maximum registrants based on this custom field as opposed to a global max.

In my case my I have three time slots, but a max registrants of 20 per slot. Right now I need to set the global to a number and keep an eye on the total for each slot. Time intensive.

Just wondering I would find it VERY useful.
