How to edit (empty) Ligatures Stylistic Set?

I want to use a different ligature in a paragraph style, but it is not listed with the default 'Stylistic Sets'.

Can i create/edit an empty set and add the other 'And' ligature? If yes, how?

OpenType ligature not in list of available stylistic sets:

Edit:

Looks like it has to be edited in the font itself.
