Tech note on printed setlist

I'd like to be able to add the tech notes as a printable field on the setlists. 

I'm using the templates to print separate setlists to band and crew and would like to be able to add details as guitar tunings, production notes, special instruments and alike to the crew setlists. 

Ideal would be to have two tech notes fields (A / B) to save different notes for backline crew and FOH crew.
