Choose which Extensible Attributes to return [ Edited ]

[#1]

Hello,

I am trying to get an object, along with several _return_fields. However, if I am to request to receive Extensible Attributes, I am unable to chose which extattrs I will get back. I am only getting ALL of them. 

Is there a way to chose exactly which extattrs will be returned?

for example, I have a DivisionID extattr associated with macfilteraddress. I wish to perform a query and get ONLY this extensible attribute in response

GET {{ipam_url}}/macfilteraddress?_return_fields%2B=extattrs.DivisionID&*DivisionID~=SOME_VALUE

But I get ALL the extattrs back.

Thanks for your help!
