Zoho Books integration with Zoho Project should not require Primary (external) Client to sync

Zoho Books integration with Zoho Project should not require Primary (external) Client to sync

The current integration workflow between Zoho Projects and Zoho Books requires every Zoho Project to have a Primary Client before it will sync to Zoho Books.  I am at a loss as to why this workflow was created this way.    We have many projects in Zoho Project that are all internal - none of them have an external Primary Client user.  We still want to track Profitability for these projects in Zoho Books and want to sync them to attach bills, invoices, etc.  However, because we don't have a Primary Client I now have to go through 50 projects and add a "dummy" client to each one to get them to sync.

Can someone from Zoho please talk to the Product Managers in charge of the integration and ask them why they made this requirement?  What difference does it make if an external client has access to the project or not - those projects should sync to books regardless.  Am I missing something - because to me this just seems like an unnecessary requirement.

Thank you!
