The problem of related relations and dynamic/static values for objects (map of relations - nodes)

I have problem of related relations and dynamic/static values for objects, eg. Car Rig PRO kit have some "template" blendermarket.com/products/car-rig-pro-blender-kit The proedure is to connect key elements of car body to the template, then panels values are interactive as properites, etc. But these elemenets of body and the templates have own relations, etc. Blender colorizing these values in some way, but it's hard to recognize where and what is in this type relations. I'm not talking only about this addon and pratice. If I have some biger project around this type, where are some constraints, limited moves, etc.. I often can forgot where, what, why..

For this problem I looking something like map of relations - nodes, where this graph building some completed project (not for material, just relations, functions). The outline looks like not enough to operate around this problem, and not helping to understand this type. Or exist some way to resuce situation if we meeting this problem?
