Is it possible to limit the submissions of my form using a ticket quantity instead of the submissions counter?

I am implementing a registration form for people to sign up to see a free movie screening. The form asks how many tickets they want to reserve (they get up to 4). How do I setup the form so that no more than 125 tickets get reserved? The current submission limit is a problem because it counts each submission as 1 when it could be counted as much as 4. If I were to setup the submission limit as 125 and every submission wanted 4 tickets then the limit would really be 500 tickets which is way too many. Vice versa, if I set the submission limit to something like 30 and then each submission only wanted 1 ticket, well then I would only be giving out 30 tickets instead of 125. Im not sure how to setup the ticket limitation without forcing each submission to account for only 1 ticket. 

Unfortunately, you can control the limits of a form only by the number of submissions and/or an expiration date.

In this scenario, you'll need to disable the form manually when the 125 tickets are reserved. Or if you want to control this with a submission limit, then you'll need to allow only 1 ticket per submission.

Let us know if you need further assistance.
Thanks.
