You must be comfortable installing GreaseMonkey userscripts.
This hack delivers trackback functionality directly to your Blogger dashboard. Every time you publish a post, the script harvests the title, permalink, and post excerpt (as well as blog title) and then displays a form on the "post complete" page for trackbacks. Enter the trackback URLs one at a time and hit enter. The trackbacks will be completed AJAXially.
