Scheduling headaches with sprayer cleanups killing my day

Man, I'm booking back-to-back interior jobs with my Graco UltraMax airless, but every time I switch from Emerald Urethane to Advance waterborne, the cleanup eats up a solid hour. We're in Texas so the heat makes the paint dry even faster between gigs, and I'm losing half a day just flushing lines and dumping solvent. Saw a thread on r/paintingbusiness where guys were complaining about the same thing, and someone mentioned Housecall Pro for better scheduling buffers. I've got three crews now, but coordinating drop cloths and masking between sites is a nightmare without solid routing. Anyone else dealing with this crap? FML, thought going from solo to team would make life easier.
