This would be a nice feature since many people (I think) would like book format with more than just pedigree info. I was just today wanting to do the same thing as described here.
So yes, being able to do a pedigree in book form with adding of non-direct individuals would be nice. Or another way (which the software also cannot do) is to have the 'extended family' chart be able to do book format instead of just poster. That would also suffice for many people's needs I think.
I suppose in the meantime others are exporting and using another program to assemble what they need?
