CONTROL STRIP BUTTON

I am new to Better Touch Tools but so far I am more than impressed with what can be achieved. I am using Aqua Touch Tools as the preset which I have modified to my requirements and it all works well. However there is one small thing which is bugging me as I cannot find how to modify it. If none of the Touch Bar are active i.e. the bar is blank on the right hand side there is displayed a Aqua Touch Control Strip button just coloured in no logo.
I would like to modify this button but for the life of me cannot find out where is is stored. Can anybody help.
