How about creating your place/bearing/distance waypoint. Make sure you've checked it 3 times!! Then vertical revision at your PBD +3000.
I have no idea if its possible to designate a left or right turn with that little arrow you see.
I had to do something similar on our secondary flight plan as our particular Navigation Database update did not have our company specific EOSIDs.
I would only have it as a reference pseudo-waypoint and would then go selected heading to turn left or right depending where the highest MSA is located.
