Contract line-level party role association

Hi experts,

I have a customer requirement to associate different parties with individual contract lines (for example, commission payment recipients).

I understand that parties and party roles can be maintained at the contract header level. However, I have not found a way to associate parties/party roles with specific contract lines.

Could anyone confirm whether Oracle Fusion Contracts supports party/party role association at the contract line level?

If not, is there any Oracle-recommended approach to handle this requirement?

Thanks in advance.
