c# - IdentityServer3 pre login "First Time Setup Page" -

is there way redirect page before jumps main login page in identityserver3 (mvc5/owin/katana)? here scenario,

1. user admin access mvc web app client.
2. it redirect identityserver service (but not login page first), yet check if configuration (like page title, admin id, admin password) exist in database.
3. if no preference records in identityserver, redirect called "first time setup page" first (like in wordpress first time setup).
4. user admin fills in preferences, identityserver can redirect login screen begin using first time.

many thanks.
