Considering what's left of Nick's hand, Rey would have to say his cartography is impressive enough. He doesn't have the luxury of being able to maneuver his handiwork like Rey with her... 'reports' that she used to submit to the Guard. She was never fond of paperwork, anyway. The Speakeasy and just working on her own at least offers some level of autonomy without a paper trail to worry about.

"And even then, the Speakeasy needs to be stocked manually. The gods don't do shit for me here."

Which was the point. Rey wanted to run this place self-sufficiently, no exceptions.
