I have created two tickets A and B.
Ticket A 60 pieces.
Ticket B 30 pieces.

I would like that when ticket A is sold out, ticket B can also not be purchased. Ticket B is only an upgrade for Ticket A. Several Tickets A can be purchased with one booking, but only one Ticket B at a time. Ticket B can never be purchased on its own.

How can this be realized?

Thank you very much for your help.
