Derived Outputs for Product Structures?

For 3DEXP On Premise R2022x (and also for On Cloud) OOTB, is there any EKL or Web Service that allows to add a STEP as derived output, but in a Physical Product and not in a 3DPart/3DShape?
The idea is to automate the process of attaching an already-generated STEP file in the Derived Output. Thank you.
