If you are referring to the page in the CMC, I don't think you can change that. But if you mean the webDesktop, or ePortfolio, you can make mods in the rptschedule.csp file. This is written in javascript and is similar to ASP programming. If you're not familiar with the languages, significant changes will not be easy. Look for the string PARAMETERS DIALOGS GO HERE in the file to see the section of code that handles parameters.
