How to pass custom field values from original subscription to consolidated subscription?

Summary:

We need to create a subscription from OM through payload. Once order submitted and subscription gets created in OSM in draft status, we will add custom field values in subscription product lines. We put Renewal process as Auto and check box Consolidate Subscription in Renewal Template. We are using Custom Field attribute to consolidate the subscription. Once we run the ESS job to create consolidated renew subscription, it's creating one subscription with multiple product lines. But, custom field not passing from original subscription consolidated subscription in a product lines.

Can we have any solution to pass custom field values from original subscription to consolidated subscription at header/product level?
