Reforging bench and liquids

When you go to upgrade your liquids, lets say Diluted giquid guilt to Diluted luquid greed. you can put in 30 guilt, but every time you click reforge, it only makes 3 into 1, and in order to do it again, i have to remove the greed that i just made.
I suggest either making the stack of greed, able to stack to 10 in the bench, so you can click multiple times, or make it so that you can put in 30, and click once to make it into 10 of the liquid youre trying to upgrade to.
