SAML SP initiated SSO URL for okta

Hello everyone,

We have a scenario where we integrate various SAML IDP systems in Okta. So we were able to login to Okta from different IDP systems as long as it is in IDP initiated mode.

Can we also build an SP-initiated SSO URL for okta which can redirect to required IDP login page(maybe using an IDP parameter in URL)? Please suggest.
