Automatically creating PO from PR using a user defined document style

Summary:

We have a requirement to automatically create PO from a PR with an user defined document style. To achieve this, we have created an user defined line type. The same line type is attached to our user defined document style.

We create a PR from a smart form which has the user defined line type and the negotiated flag is checked. The PR has the Supplier and site details populated. Once the PR is approved, the PO is created automatically, but the PO is getting created with the standard document style.

Is there a way we can have the PO created with the user defined document style instead of the standard document style.
