Bleeding master cylinder in the car

I just finished a brake conversion and bench bled the master as per the instructions. It was a ***** removing and replacing in the car because of the brake pedal linkage but it’s done. Now , while bleeding the brakes, I ran the master dry, like a dumb ***. Can I bleed the master in the car this time pumping the brake pedal?
No way I want to rip this apart again.
