In all cases of tonicization I decided whether to notate a brief tonic change or not (piece by piece, case by case): https://rawl.rocks/s/applied/chain_of_dominants
You can always manually "probe", minutely "recolor": click on a measure number and hover a potential new tonic.
OK, so this is a case of personal knowledge transfer, which is valuable for that reason. You take your expert opinion that certain things are happening functionally in the music, and encode it in color.
