Promotion of a REC to a Library

Hello,
In the Capella 5.1 contextual Help, section REC-RPL Advanced features, it is mentioned:
"From elements of a model, it would be possible to create a REC into a referenced library.
Elements will be copied into the library and become a REC and initial selected elements will be considered as a RPL of the REC stored in the library.
This feature is not available yet "

This mention was already present in Capella 1.4.x.
We see this feature as a very interesting one in the context of platform’s development.
Is this feature planned in the Capella roadmap?

Thanks for your answer.

Hello. This feature is not foreseen to be developed by us in the near future. I guess that it could be the subject of a specific development.
