The problem with being able to add the setback automatically is due to limitations with Roll20. HTML (the code the Character Sheet is written in) does not allow for If-Then-Else statements (that I have found). There is a method to use that sort of logic in normal webpages but that involves inline Java Script. This is not allowed on Roll20. Now Java Script is allowed, but as methods after. So if the character sheet applied the additional setback to Piloting Space it would apply this potentially to all piloting space checks, even ones in different ships. In order to do one "per ship" there would likely need to be a specific roller on the Vehicle sheet manipulated to account for the handling. I started working on the fixing the Sheet 1 month ago, and have not had the time among the other requests to get to this. I will "add it to the list" of things to improve.
