Disable autofill from overriding non-login page form fields

Question

I work in a CMS where I have to edit user profiles that include the Username field. Any time I open one of those pages, LastPass autofill replaces that user's Username with mine, and (⌘Z cannot undo it). Is there a way to limit autofill to the login page of a specific domain, but prevent it from engaging with fields internal to that domain?

Please fix this.

This has nearly caused some pretty serious consequences by filling in fields that are not related to the login, and not related to the user name field specified in the vault entry.

* URL rules do not allow me to specify anything more specific than "host rules", I need "exact match" as an option. 
* Never URLs do not respect anything below the domain if they do anything at all.
* "Edit form fields" adds a bunch of redundant fields, but still applies to fields that are not listed.

It still does this.

Even when the url is not the one set in the vault, and even if the field is called SystemUserName.
