Rachael,

You can assign the PG Dynamics plug in to the audio in Biab. Uncheck the box that opens in the Dynamics dialog box and manually set the boost level there, you can go to +24 db's there. It will boost ALL of the audio tracks in Biab, but you can adjust each real track's db level on the Biab radio bar.

Opt/Pref/Audio/Realtime DX Plug ins

That should boost them without needing any outboard gear.
