The helpfile for BIAB2014(380) describes how to "Lyrics". It also describes how to add "Section Text".

Using my homemade MIDIfile analysis app (from http://tima.uk.com/midianal.htm), I can see that the "Lyrics" are stored as as the midi data type 'Lyrics'. And the entirely separate "Section Text" is stored as the midi data type "Text".

I suspect the functionality required by the OP is to *automatically* convert the BIAB chord nanes to be used in BIAB's 'Section' texts. Until then, perhaps it can be done manually (as described above).
