Spellbook for esoteric polymath bard?

[jrcchicago]

Is there a toggle I’ve missed that would allow me to select “Bard” on the Spellbook Header Helper Table when I buy a spellbook for my polymath bard after giving him the Esoteric Polymath feat? When I go to select a spell, they all appear in red as errors because nothing matches the spell list associated with the book (because there isn’t one).

This is for a non-remaster 2E character (although the spells added automatically have changed, inspire courage and unseen servant have been replaced with courageous anthem and phantasmal minion in his spell repertoire, but not in the spells available to select from).
