A feature for the radio buttons so that they can be limited to an amount of submitted values.
f.ex. a radio field with 4 times:
Time slots before form submission:
choice 1 = 9-10 -> 4 available spots
choice 2 = 10-11 -> 4 available spots
choice 3 = 12-13 -> 4 available spots
choice 4 = 13-14 -> 4 available spots
Now "User 1" selects time 10-11 pm
Time slots after form submission:
choice 1 = 9-10 -> 4 available spots
choice 2 = 10-11 -> 3 available spots
choice 3 = 12-13 -> 4 available spots
choice 4 = 13-14 -> 4 available spots
I understand that you want to limit, hence also modify, a field (radio) according to certain entries in your database.
I think, this is subject to custom code or/and using several features and tools together.
A Custom Field that natively does this, would require several queries (which you need whether or not you'd use custom code/inbuilt feature), with the potential of slowing down a site remarkably.
Additionally, the GUI to set such conditions (how many spots, by how much the decrease should be, etc), is asking for a totally new approach and settings that are not present as such yet in Toolset, and not planned.
Here, in this case, I would rather recommend working with Post Relationships because there you would have possibilities to connect each post uniquely for example and never re-use it, or limit it's possible connections to a certain amount and more.
To get assistance with this, you can ask in our Forum for help (in a separate Ticket)
I have filed the request, for now, to be upvoted, and I generalized it a little:

Please let me know if it matches your request.
Thank you Beda for you qualified reply and I wish that there will be some backing for this feature.
Not so likely but one can always hope 🙂
I found this addon to gravity forms might be used as inspiration:
