Add attributes to the Subject NameId

Is it possible to add attributes to the NameId element in the SAML Response?

The service I am integrating with requires the following structure:

<saml:NameID Format=“urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified”
NameQualifier=“ "
SPNameQualifier=”[my-url]"
>orgdir=medicash;ecid=XXXXX</saml:NameID>

I can set the value by mapping it “orgdir=medicash;ecid=XXXXX” but I cannot set the “NameQualifier” and “SPNameQualifier” attributes on the NameID element.

Many Thanks
