Hi Hekspoilr
This could be solved using VBA but
Given the fact that your voting spreadsheet is online, I'm afraid the macros would not perform on online excel files.
So a suggest you try to use Microsoft Forms.
Check the video tutorial for a quick inside the Microsoft Forms
and in your case at minute 2:00 the "Choice Option" is the one you might need.
