Link Sage Intacct Bills to Subcontracts / Purchase Orders

I have had a customer request that Sage CM be able to link / attach AP or Purchasing Bills from Sage Intacct to Purchase Orders/Subcontracts in Sage CM.

Use case for this is the customer is currently using Sage Paperless Construction for entereing all of their ap bills. They have complex routing rules setup in their that they wish to keep. Sage Paperless sends the bills to Sage Intacct. If the customer wants to use Sage CM for creating / tracking the Subs and POs they would have to re enter the bills in Sage Cm and then not export them to Sage Intacct.
