Can Google Forms Limit Signups for Each Time Slot?
Set a separate capacity for every shift on a free Proximatic signup. Full jobs stop taking places while volunteers can still choose the work that needs help.
Your welcome table needs two people. The packing crew needs six. Closing a signup after eight responses still leaves you short if six people chose welcome and only two chose packing.
Limit each job, not just the whole invitation. In Proximatic, set two places on the welcome shift and six on packing. Volunteers see the work, hours and available places. Once welcome fills, it stops taking reservations while packing remains open.
If packing has two names on the roster, you need four more people for that job. That's the request to share. The next volunteer can take an available place directly instead of choosing welcome and waiting for you to explain that it filled yesterday.
The numbers stay attached to the work as plans change. When someone cancels a signup, that place becomes available again on the event. You can keep sharing one link while Proximatic handles the reservations and you concentrate on finding the people still needed.
Create a signup with time slots. Google's response guide covers its form-wide controls.
