It would be nice to be able to set the rate of mod effects ( i mean chorus and phase, here) and then have a 'phase' or 'manual' parameter which you can link in the mod matrix if you like, so you can move about the fx as you please...
Maybe somebody already knows a good workaround you can use at the moment...?
... But what about the chorus effect, nothing on there does that (actually i think the chorus is lacking a few of the 'triaditional' chorus effect controls...)
