Hey @Atmedia,
Thanks for reaching out!
This is unfortunately not possible. 🙁 You could, of course, set the stock of the ticket to “1”, but to make it impossible to set it higher than 1 is not something our plugins do on their own.
So to implement the features you describe, you would have to write that custom code or hire a professional developer to do it for you. We have a list of great developers here → http://m.tri.be/18k1 (and have no affiliation with any of these folks—they’re simply some well-respected names in the community that we’ve compiled to share in situations like this one).
Thank you,
George
