The driver can update any of the displayed metadata. And you can use metadata plugboards to fiddle with some of them to allow you to use other metadata from your library. I use this to put the tags, page and word counts, and reading status in the synopsis/comments.

As tags are not displayed anywhere on the device, as @PeterT suggested, you can create collections from tags. How useful that is depends on how good and how many tags you have. They are probably more useful for genre. If you want to see them in the book list, the subtitle is probably the best bet.

Also, is there a way to preserve the original subtitle in case the epub already has one? I mean I may want to concatenate subtitle (if present) with genre and publish date.
Subtitle is not one of the core metadata items. Most subtitles are included in the title. Kobo has a separate field for it, and may populate for purchased books.

The driver in calibre can update the Subtitle for books, but, it is brute force. It compares what is produced by the template with what is on the device and replaces what is on the device if they are different. Updating an existing subtitle by adding something to it is not really practical. How do you know what part is to be changed the next time the update is being done?
