Please Make Keltner Channels Adjustable

It is a super easy fix.
Right now the r multiple can only be adjusted by 1.0.
So keltner channels can be 2.2 or 2.25 r multipled, like I want them to be per Adam Grimes/Linda Raschke technical analysis method. This would be a super easy fix. I do not know coding so I am hoping your dev team can please include this…
