Modifiers for wacom

maybe this has been discussed and I appologize if I am repeating a question. 

By chance is the ability to create modifiers while using my WACOM MobileStudio Pro 16 coming?

What I mean is, in Photoshop I can set a button to perform a specific task, such as increase my brush size. 

I have tried to set a button in Fresco as I need the ability to adjust my brush size and waterflow for my live brushes. 

Currently I have to keep going back into my toolbar and manually adjust brush size and water flow every time. It's exhausting. 

Again, if this is a repeat problem, please forgive me and point me in the right direction

Sincerely

JustBob
