QoL change to sell multiple units of an item at a set quantity

[Juun]

There should be a option to BUY specific amounts. Cuts out all the listing issues.
Doesn't matter if you put up 20, 50, or 900 items... people can take from that stack as much or little as they need.
The only thing a seller should do it check a "allow shaving" box, meaning buyers can shave off the stack custom amounts.

But that would lower the overal price of an item. I could put up 10 single stacks for 1000 gil and get more money then the guy that put up 99 for 100.
