One option you might consider -- particularly with longform projects -- is a Fixed Node Tree, where you have X number of labeled nodes that provide the same function in every shot in the entire project. 90% of the time, these nodes might be bypassed, basically doing nothing, but you always have the option of rippling a change just to those specific nodes in the middle of the tree and adding that precise correction.
Here's one example of a Fixed Node Tree, as used by veteran LA colorist Mark Todd Osborne:

I use variations of this idea in my feature and longform TV work, specifically so I can make one similar change in the middle of a node tree for a selection of shots. It also helps to have certain kinds of windows (deactivated) ready to go, should you need them. Note the Vignette that Osborne has at the end of one row.
I also like the idea of having all the nodes pre-labeled. That way, if you happen to come back to the project 3 months later, 6 months later, or even a year later, you can pull up the session and immediately know what was done and what function each node was doing, without having to "hunt" for it.
