Changing 4 or more Current Attribute Numbers

I know, I posted similar questions before, but I need a little more detailed answer than "use API". I been unable to figure API at this time. How can a player apply damage to a specific Current Attribute with 4 or more choices, without having to manually doing it every time in the character sheet? For example, a vehicle take 10 points of damage to the right side. Vehicles have six sides that can be damaged, but in Roll20 their are only 3 bars to track this.

Sorry, but there is no way to alter attributes without using either the 3 bars, the character sheet, or the API. If you are having problems with the API I suggest posting a request for assistance in the API forum. Perhaps you can ask the API forum if someone is willing to write a script for you.

Thank you.
