That's what I do, minus the inventory. I save all the different sized Ziploc bags I get from Pinball Life. I put all the parts that go with a ramp/plastic together. I also line up the sections in the order I took them off and reverse the order when I put them back on. This can be helpful for games where taking parts off in a certain order makes things much easier.

I'd say it's usually pretty obvious where stuff goes unless you're removing all the posts.
