[ORD 2021 R1] COGO Point PT Layout From Radius Point

Wow,... I could whip this stuff out in InRoads SS2 ... but I digress (it's a bad habit of mine these days living in a COGO world)

I cannot figure out a way to layout Point #9 in this diagram. I've laid out Point #6 (the POB), Point #7 (the curve PC) and Point #8 (the radius point) ... but I cannot figure out a way to layout Point #9 (the PT). All I know is the Radius and Arc Length (shown on the diagram).

Ya, I know I can use another program to calculate the angle. And yes, I can layout the actual Curve line with an Arc command. But I'm laying this out with COGO Points ... and THEN will lay out the alignment (Ruled to the COGO Points). I wish ORD had a real Traverse tool.
