That would be really nice! Maybe one could use a similar syntax as 
LibreOffice? That would be

        #:roman "Vollkorn:liga=0&ss13

for disabling liga and enabling ss13.

I just realised I can override grob the grob property font-features, not 
only markups. So I’ll adapt snippet 443 from the LSR for now 
(http://lsr.di.unimi.it/LSR/Item?id=443). In my use case I don’t have 
markups, headers, page numbers etc. so this solution should be sufficient.
