Default Fade In and Fade Out Amount VSE

When adding a default fade on right clicking a strip and clicking Fade In and Fade Out, blender applies a default fade amount, but there is no way to change the speed of the fade unless manually clicking "To Current" or "From Current" - but that requires constant fiddling with the timeline and counting frames. I want something that applies to many strips quickly. The default is 30 frames! Sometimes a quicker fade is much more appropriate.

There should be a way to set the amount this default fade in is.

Maybe there is a way to do it with the compositor as an easy parametric node group?

Thank you
