In Moodle, can we add our own Resource Parameters to be sent along with links?

Please answer this if you can, and then retag it as Moodle. Thanks

To clarify the question, a very nice feature of Moodle 1.7 (perhaps earlier) is that when you add a link to a site, you can specify that you want certain Moodle Parameters to be sent along with that link on the URL. The fields you can send include the list below. This question is whether or not you can include any other variables that we might need such as UCLA subject, course number, section, SRS#, etc.
