Can we create contract without Primary Party and add at a later stage in the Draft

Summary:

We are looking to make the Primary Party field in the Create Contract pop-up as non-mandatory and create contract initially without a primary party. Tried using Page Composer to make Primary Party as non-mandatory but was unsuccessful as edit properties option was disabled for the specific component.

Content (please ensure you mask any confidential information):

We will authoring the contract in Fusion but using an external system for tenders where the draft of the contract will be made available as part of the Tender documents. Once a supplier is awarded the contract in that system, we will add the supplier in the contract and further fulfillment will happen from Fusion.
