How to set default color, pallet or color mo for drop shadow?

I've recently had to really dig in with the CDR 2022 Mac Version but have run in to a question that seems to be on both the Mac and Win versions (I have to float between both regularly).  When I go to apply a  shadow using the shadow tool, 99% of the time I need it to be an RGB 100% black shadow that I will manipulate.  I have my Primary Color Mode set to 'RGB' in my color management settings, but every time I got to add a drop shadow it begins with CMYK black, so I always have to go up and select "RGB" and that gives me RGB Black 80%, so I have to select the full 100% black swatch.

Is there a way to lock this in to RGB Black so that I don't have to change it every time?  I thought if I had my primary color mode set to RGB that would do the trick but no luck.

Thanks in advance for any recommendations!
