Is it possible, through a plugin or custom work, to add an inventory feature to Gravity Forms? I've been trying to bend Cart66 to my will with GF, and I just realized that if GF had an inventory tracking feature inside a form, it would make my life 100% easier.
For example, I run a murder mystery dinner show with a specific number of seats per show. People fill out the order form and specify the number of seats they want before submitting. Getting this information to carry over to Cart66 with all the miscellaneous info required has been a huge hassle, but if everything was done in GF in conjunction with the PayPal/Authorize.net payment plugin, it would be incredibly simple.
