How to integrate support for title header and keepassnatmsg.

[f1h0]

How can I integrate this Google app so that KeepassX can use header capabilities as a rule for URLs?

What should be the result:
There is a website
where there are more than five accounts with the same URL except for different texts in the headers.
I want to use this as a rule so that KeepassX will automatically fill in only one account that matches the header and URL. It's convenient, it's incredibly cool!
