I had a feeling that might be your intent. No, the H90 can do a lot of things, but a successive buildup of composited algorithms isn’t one of them. That would be a nice concept, but the closest you’ll get is combining two multi-faceted algorithms together.
This isn’t as limiting as it appears initially. I consider most – if not all – of the algorithms as “multi-effects”. That is, a dual pitch shifter might also have delays, detuning, EQ … A reverb might have several types of modulation, etc.
