Part of it (at least), @Moonbase59.
I was not aware of the ’x-cardhop’ thingy, but was able to make a Keyboard Maestro macro, which asks for first and last name and puts them into a string, which gest pasted to Obsidian note. Good enough.
[In Cardhop](x-cardhop://parse?s=%Variable%Etunimi%%Variable%Vali%%Variable%Sukunimi%)
Sorry about the Finnish variable names 
Only wish it would be possible to grab the note title on runtime…
