hi
as a quick fix for you, before the option is added, you can do this to speed up your greening.
when you are in-play and ready to green up, have one finger on the enter button on your keyboard and the other hand on the mouse.
now when your ready to green up, press the left mouse button on the greenup icon, if the message comes up, then quickly press enter with your other finger, hey presto a very quick clear the message and ready for the next greenup try.
