Pop-up based on seats

Hello everyone,

Has anyone found a way for a "notes" field to pop up based on seat location?

For example, when a patron purchases an ADA seat online, a popup would generate in TNEW that would ask if they have any notes that they would like to communicate to the box office (not a mandatory field, just an option). Ideally, it would open a CSI if they typed anything in the field. We are pretty sure that is it not possible to do this in TNEW.  I would love to hear what other box offices do in regard to this or how they go about recording necessary info from patrons based on seat location!

Thanks everyone!
