Double and triple synths

There is a growing desire that 1-star recipes be granted the ability to quick synth, which I have mixed feelings about. I would like to propose something that could be a better alternative if the dev team does not wish to allow quick synthesis of 1-star recipes.

What I would like to see implemented, is the ability to unlock a double or triple synthesis on 1-star recipes. By double/triple synth, what I mean is something like a shiny new button above the "synthesize" button for a recipe, that will allow the recipe to be doubled or tripled. All necessary materials will also be doubled/tripled, so the real saving is in the time it takes to synthesize.
