F.i. i have used Cubase PRO for that:

Import a Midi file, let Cubase analyze the chords, easier when you know the key already.
Also works best if there's a string section playing simple chords. Sometimes you need some manual correction.

Export the chords as Midi file, and usually that speeds up import procedures a lot when importing these midi files songs in to BIAB.
BIAB handles a 2 bar intro space usually, but you still might correct the importing offset there.

You might have to experiment with BIAB's quirky way of handling Verses, Choruses and middle-8 arranging.
BIAB calls the whole caboose Chorus, which can be confusing.

(BTW still have my spare Cubase Pro 10.5 license for sale BTW, comes without 21% VAT for buyers outside the EU).
