Is your feature request related to a problem? Please describe.
There is no easy way to sell 1 item at a time in a stack.

Describe the solution you'd like
On right click, sell one item at a time, On left click sell the whole stack.

Describe alternatives you've considered
Splitting the stack into smaller stacks or picking it up and right clicking to put down one to put in, but that is much less efficient than having right click signify, sell one.
