Suggestion to change the flexibility of Mythic Tome Farming

[Entheogen]

I would like to start this thread off with the fact I'm perfectly ok Farming Mythic tomes and am not suggesting a way to make endgame gear obtaining "faster" or "easier".
I wish there was some way to either save up the 300 allowances similar to the way leve quests are. I'm not asking for a way to earn them "faster" just a way to put increase the pool cap by putting it on "hold",I feel that as FFXIV is trying to cater to both casual and hardcore players it seems a bit counter intuitive to introduce a cap mechanic but I realize it has it's place. What I'm asking for is a way to put your tomes on "hold" allowing you to gain a larger pool to a certain point (900 seems reasonable). This way if for example a player can't log on or perhaps is trying to promote a positive community by helping other lower level players they are not penalized for doing as such. If I didn't explain something in my idea thoroughly enough please feel free to ask.
