Health monitor inheritance with NTLM

I'm not having luck finding other threads about this, so it must not be used like I imagined.

One of our server teams is moving to a new standard that would require all traffic to provide valid authentication credentials in order to reach a server. For user traffic going through the LTM that's no problem, but it means that our health monitors all need to have a username and password to them. This all works fine, but in an effort to avoid having to give service account credentials out to everyone building pools and health monitors I wanted to create a "template" monitor that has all the proper curl syntax as well as the user credentials we were given to hit the servers.

However, I noticed that when I select this "template" monitor as a parent, the username is populated but the password is lost. I realize this has got to be by design (for security reasons), but I wanted to ask if anyone had tried something similar or would be willing to share their thoughts on a way to achieve my desired result.

Any thoughts are appreciated.
