PO Integration between Vista and TP

Need to have the ability to sync and integrate POs from Vista into Trimble Pay. We have Procore project management and with the limitation of one integration into a project we need to have this be Vista in order to allow automated syncing and currently that means our vendors who have been invoice POs for 2 years in TP due to us previously having the integration just between Procore and TP when we had Sage accounting need to have the ability to sync our POs from Vista into TP like we have with the ability to go from Procore into TP.
