Create URL to Search Results in Spreadshirt's Flash Designer

I'm not even sure if this is possible, but i'll try to explain... [login to view URL] This is the Spreadshirt custom designer. If you click on 'Choose Design' you can enter a search term. for example if you enter 'teesontap' you will see all of the designs tagged with the term teesontap. (My designs). What I want to do is create a link from an external site which when clicked opens up the spreadshirt designer with all of the results for teesontap on display, as if the user had just opened the designer, clicked on choose design, then entered teesontap into the search box. Is it possible?
