Can DOpus batch edit jpg files to embed filenames in metadata?

I'm new to Directory Opus, so my apologies in advance if this has been asked elsewhere.

I'd like to batch edit the metadata of many (1000s) of .jpg photo files so that the Title, Subject, or Tag field of each photo is the photo's filename. In other words, for each photo file I want to embed somewhere in the file's metadata the name of the file. Can Directory Opus do this? I've looked through the manual and played around with the program, but don't see how it can.

Thanks! I'll give it a whirl. Where is this and other types of commands described or disclosed in the program's documentation, so I don't have to post to the forum in the future?

Click the small Commands link at the top-right of the page here.

You can also push F1 in the command editor within Opus.

Got it. Thanks again.
