Load User Webpage on Webserver start

I've developed a webpage that I would like to load as soon as I put the IP address of the PLC into a web browser (i.e. https://192.168.1.50, etc.). I don't want to have to navigate through all the Siemens webserver pages. I see this can be done on the S7-1500, I was wondering if similar functionality is available for the S7-1200. I checked out this Siemens link to add the login/logout functionality to a page. That works somewhat.

The logout functionality works perfectly for the S7-1200 but the login functionality doesn't get given an opportunity to run because one cannot access the user defined page directly (i.e. https://192.168.1.50/awp/Application%20Name/mainpage.html, etc.) . The S7-1200 webserver always defaults to the Siemens home login page (https://192.168.1.50/Portal/Portal.mwsl?PriNav=Awp) when a user is not logged in, even if the login functionality is available on the user defined page. 

Hello,

Since S71200 V4.2 and Step7 Basic  v14 , user can define "user defined we page" as starting page like S71500. See the attached screen shot.
