Route Summarization Policy support for OSPF

[RemcoVroman]

On the external epg of a layer 3 out I want to apply a Route Summarization Policy. On the datamodel I only can find to set it to true or false. But I cannot find the place to set the policy name and I cannot find the code to create the ospf policy (Via guide set via Policies => Protocol => OSPF => OSPF Route summarization)

I understand that it is only supported for BPG at this moment. Is it possible to implement it for OSPF as well ? We use this feature in our customer ACI fabric.

Best regards,
