Tracking Seat Naming Opportunities via Future Performance?

Hi all,

I'm trying to develop a way to track seat naming opportunities across our venues so that our dev team can quickly see what seats are named and what are still available for naming--we're currently working from excel spreadsheets which are unwieldy and prone to error. I unearthed a few threads from 5+ years ago where some folks mentioned using a dummy future performance to track what seats are available and who has named what, but they were scant on details.

Does anyone have any experience with this who would be willing to share?

Thanks!
Grayson
