How do I allow a player to edit a spaceship they own? Mongoose Traveller 2e

[sirlark]

I've just started using FGU and we're manually copying over a campaign from Discord/Google Docs/Excalidraw. The PCs have two ships in their possession. I'd like to allow the players to manage the cargo in each of their respective ships. I can't figure out how to unlock/pass ownership to a player of the PC Spaceship entry
