Is there a way to confgure a different IdP logout URL in the PicketLink Service Provider configuration?

So far I've discovered that the SP tries to use the <IdentityURL>${idp-sig.url::<idpur>}</IdentityURL> value defined in SP's picketlink.xml file as the default logout URL.

But in some cases the IdP has different URLs for login and logout handlers.

Help is greatly appreciated.
