Search for Headline meta tag

Question

Is there a way to search for Headline in Bridge's Search function?

I thought there might be a way to enter my own <tag>, but I don't see that either.

Here's why:

These are the fields in Bridge's Metadata. Headline, Description and Keywords are nicely clustered together in the IPTC Core list. Title is on the list, but further down. Not a huge deal, but less handy depending on how screen space is arranged.

I read the distinctions for these in https://photometadata.org/META-Resources-Field-Guide-to-Metadata. I think my usage is consistent.

Now let's look at fields in Bridge's Search. The available list is much reduced. Headline isn't even there and Title is called Document Title. So there's the question: How can I search for just "Headline"? (All Metadata will capture it, but that is obviously undesirable for some searches.)
