Ldap search priority for specific client

Hello guys.
I am wondering if keycloak will support ldap search priority configuration based on client.

My use case is:

1.Multiple applications (Ex. application A, application B) in the same realm (to support SSO between the applications)
2.The realm enables user federation by adding two ldap (ldap A, ldap B) server
3.When user login through application A, it should search user in ldap A first if user is not found then search in ldap B.
4.When user login through application B, it should search user in ldap B only.

As I know, currently keycloak only supports global ldap search priority by specifying its priority in user federation tab.

How can I manage to do that or will it be implemented in the future? Thanks !
