they do make trims for sa. it replaces the midstage eq and can either put a "smile" or a "frown" in the signature. these are almost always for use with deep cascades, not 5 deep. a system without fiber feed with a 30 deep cascade would benefit from trims.
luckily, sweep was invented for just this type of problem. sweep is basicially a comparison of how all frequencies react in comparison to each other. since insertion loss on cable is a linear formula as a function of frequency, all (decent) sweep responses should be fairly smooth, no big dips or roll-offs. of course, taps dont play fair and can cause extra low-end and high-end roll-off but this isnt easily confused with mid-band "humping".
your print should have input levels for each active calculated for you. anytime your input levels are 3 or more db off from calculated, a red flag should go up. i would bet that your high-end is off about 8 db or so at one of these actives. sometimes, when you add a few taps in a run, or drop the tap values (hot tap) for a couple of spans, your high-end will be off a couple db, but your sweep should still be fairly smooth, although your tilt will be more negative than what it should have been, so again, this isnt easily confused with mid-band "humping"
i would not, for any reason, adjust your output levels from design to fix a response issue, especially on 5 deep. you may be overdriving your first stage hybrid and this is screwing your signal, but the mid-band "humping" causing this is most likely in a tap or cable.
