Feature request: FriendlyName flag

Some SAML SPs are looking for FriendlyName in the Attribute properties in the SAML Response, rather than Name:

 <saml:Attribute Name="firstName"
                            NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:unspecified">

Is there a way to set this property to FriendlyName? If not, could this be set an .env var?
