There are technical problems preventing them from implementing something like this and iirc the reason is twofold
1.) The way glamour plates work is super unwieldy and they dont wanna give the game migraines juggling changes from plates in a busy area where people aren't doing simple things like shopping in Limsa or listening to someone /perform.
2.) Devs found out that if you're attacked while asking the game to read data from a glamour plate that leads to really weird issues were the game reads or writes the wrong data.
Other problems crop up if someone uses a macro that would change their glam during an attack and can change even sometimes rewrite what function your commands perform.
So they circumvented the problem by stopping players from interacting with glamour plates in combat possible areas, and this is also why they only let you edit plates in small instanced personal rooms like at the inn or in your grand company's squadron room.
