Yes, you can manually edit all tags with the tag edit dialog (right mouse in tag list window - Modify Tags) or you make it with this macro (modify the 2 paths according to your installation):

Don't forget to enable the macro property Continue if a Find with Replace not found which must be set for this macro.
The macro saves the modified taglist file to a new name. I think this is better than modifying the original because the Taglist.txt file is always updated during an update of UltraEdit. Although the update is done with a notification and creation of a backup, many users have a compulsion to click on OK buttons without reading.
To use this new modified taglist file instead of original open the modify tags dialog as described above and click on the Browse button to select MyTaglist.txt.

Or look at use-submitted tag files page of this website. There is an updated tag list file for HTML named HTML Tags and Entities - 03/23/2007.
This tag list file contains both, a group with HTML tags in upper and a group with HTML tags in lower case and some other HTML related tag list groups.
On the download page is also a link to a README.TXT which describes how to modify the tag list file.
