Revamp Materia Transmutation for QoL

Hello, I like to use the Materia Transmutation NPC in Central Thanalan, however I find the use of this feature unneccessarily tedious, and so I would like to see this feature upgraded to be more time efficient, I would like to be able to lock in 5 different materia types to use for multiple transmutations, creating up to 50 new materia in a few moments, instead of needing to supply each of the 5 materia for transmuting 1 new materia every single attempt, it gets very repetitive and since the outcome is usually in my favor due to mechanics already part of this feature, I'd like the tedium of the feature to be made more efficient, since I have already done the work in collecting 5 materia, I feel I should not have to confirm every single time i want to create 1 new materia from 5 i have already put hard work into collecting.

I would also greatly appreciate having materia transmutation NPCs added to all major cities in the market areas, or add this functionality to the Materia Melder NPCs already in all Major Cities

this would be greatly appreciated, and if you think creating 50 new materia is too many, I would be happy with 10 at a time.
