Question regarding sending attribute from SP to IdP

We need to reply to Shib SP from Shib IdP with an attribute from ldap, however this attribute depends on the specific request that is coming to the SP.

Is there a way to send a custom attribute from Shib SP to Shib IdP for example inside authentication request or similar which can then be parsed by IdP and determine which ldap attribute needs to be released based on the custom value IdP received form the SP?

Thank you.
