This isn't a good solution to the problem described here, but I thought I'd mention it anyway for posterity. If you give a query a name and save it, the roundup core assigns it a database ID. You can then go to http://tracker/queryN to go to that query. You'll still need to click submit on the form to see the results but all the fields will be filled in for you. Unfortunately, I don't think there is an easy way to find out what N is for any given query. If you go to http://tracker/query it will you show you ALL queries (and their database IDs) so you can look through that list and find out which one is yours.
