F5 integration with SAAS applications

Hi All, We integrated F5 SAML with 3 different SAAS applications. Our issue is when ever a user logoff from one application will actually logoff from other applications too.

But we are looking for the below solution - 1. when userlogin to one application (through the iDP) should allow the seamless login to all other SAML based apps and 2. when user log off from an application it wont log off all other applications ..

is this possible in F5?

Thank you
