Can we map EFFs in PIM to custom fields in Sales Product Catalog?

Summary:

We're looking for a way in which we can map EFFs and their values set up on an item in Product Information Management (PIM) to Sales Product Catalog. We're currently using the OOTB scheduled process, namely: "Import Sales Products from PIM Data Hub".

However, the EFFs do not get mapped, which is understood, because we haven't defined a "mapping" somewhere between these EFFs to custom fields.

Question is - is it possible?

We want to pass these items with the respective custom attributes to CPQ for the consumption within the quote and ultimately into Orders and Subscriptions.

Thanks,

Akhilesh
