Possible to use degree of curvature to define circular fillet without converting to radius?

While I am running OpenRail 2021 R1, this is just linework.

Is there a way, either a dgnlib edit, or a vba function, that would allow me to input, for example "d10" instead of converting to radius in "circular fillet"?

I know I can do it with geometry, but when doing quick concepts, it is quicker to just use dumb lines
