Auto-Filling a Value of a Contract Document

Hi Experts!

Is there a way to auto fill the contract type whenever Contract Document Template is chosen?

I see SAP CLM has one already by default, but is there a way to change the selection?

For Example:

When I generate a contract (img1), and chose the template, I want the Contract Document Type field to change it's value (img2), depending on what template is chosen, and the Purchasing Organization that master agreement belongs to.

Thanks in advance!
