Hello!

With the way items and such are handled I don’t believe this can be a possibility. Each Materia has a separate removal rate in regards to the loss of materia.

There already exists the option to remove Materia from gear, and the maximum number of slots of Materia is 5, so adding such a feature would cause more problems that it would solve.

Many players complain of doing things they did not intend such as buying the wrong piece of gear, or teleporting to the wrong location when as many systems are already in place to avoid these instances. Please take your time and ensure the Materia you wish to remove are the correct ones.

I’m sure if this feature was added you would be rather upset by accidentally removing a piece of Materia from a brand new piece of gear is obtained and you have decided you want only one removed and ended up removing them all, resulting in thousands if not hundreds of thousands or even a million Gil was lost.

I believe removing one Materia at a time is the best option. Thank you.
