So this would be a way to speed up painting very quickly where in the shop you can click one button (see picture)

You click the button it tells you how much it'll cost to paint all of your mech one color (or you could pick and choose colors and get a preview of what your mech will look like) it'll tell you the total cost.. and you accept.. it asks are you sure.. you click yes.. and bahm you saved a little bit of time and got to see a preview of your mech painting to make sure you get what you want..
Also if this was implemented
viewtopic.php?f=409&t=26084
You could use the paint option there
Anyways thanks for reading
