Need to choose non primary bill to site and ship to site at project creation

Hello -

We have a new business unit that heavily utilizes the projects module for milestone/event billing.  When we are creating the projects for these customers, we are finding that the PM's are not seeing the correct bill to and ship to address locations.  It appears that the projects module will only show the primary bill to and ship to addresses for a customer account number.  This is large gap for our us as our TCA may have multiple bill to and ship to locations set up in our TCA.  Since the Ship to address drives tax calculations, it is very important
