ok, now I understand. Unfortunately I don't know how to do that, and I
suspect it can't without a bash script that looks at what audio cards
you have connected and does something depending on the results

but it would be nice, I too have one low latency preset for the external
audio card and a high latency one for the onboard card

oh and you have lots to be excited about :)
