Request: Add a 7th ability score to vehicles (quality)

[Sam Barrie]

In the Ghosts of Saltmarsh book, which seems to be the inspiration for most of the content in the vehicles sheet, there is a 7th score for the crew of a ship called “Quality”.
This is a bonus for things like initiative and stealth checks, can be rolled separately as its own ability check for hazards and is used as a modifier on repair checks (1dX + Quality). This score can be changed and is expected to drift up and down which makes it perfect for being a separate ability score.
