One click feature of Curve Brush. Where enable it?


#1
Hi,
when selecting the currve brushes and draw a curve with them I can apply the sculpting feature of the brush with one click on the curve. See here:

The advantage is that I do not have to drag the curve to sculpt. But when I activate now the curve function for let's say the clay buildup brush I can paint the curve but the one click feature does not seem to work. I have to drag the curve. Which leads to imperfections in my case.

Where is the one click feature for curve enabled and disabled? Can I transfer the curve features of the curve brushes to all brushes?

Thx!
