Kontakt Symphony Series expression maps - success, anyone?

I took a look on the NI forum, to see if anyone was posting about Dorico. Not so much. So does anyone have tips about setting up expression maps for the NI Symphony Series?

I’m looking at the solo flute (full version), and it looks as though there are more patches than there are slots available, meaning (if I’m understanding correctly) that only 8 can be used in a given instance. Is that right, or is it specific to keyswitching - would using cc make things more flexible?
