WPM Initial URL not recorded or retained

Scenario:

1. In WPM recorder, type an initial URL  (http://userfriendlymarketingurl.awesome.com) and start recording.
2. That URL gets redirected to an SSO (https://sso.awesome.com) system and returns a page appropriate for the now-logged in user (https://boringappurl.awesome.com/stuff) .
3. Recording proceeds with various checks, etc.
4. Recording concludes with a click on a "Log out" button/URL, which also redirects to another page.

Issues we see:

• The initial URL that is placed in the first step of the resulting recording is the redirected URL, not the one typed into the recorder.  This redirected URL includes a session ID that is retained in all future runs of that recording. 

I'm aware of the workaround in SolarWinds Knowledge Base :: SEUM may not correctly handle redirects from the first URL page.  The login page is from a purchased tool that does not allow us to modify it or add any static HTML pages that would be used for this transaction.

• Even when we export the recording, edit the XML to remove the redirected page and insert the correct initial page, import and run the recording, we're seeing the same redirected URL and session ID used.  It seems to be stored in the player's cache somewhere?

Is this a known bug?  We've seen this in WPM 2.0, 2.1 and no change in the recently installed 2.2
