Display latest tickets in worklist

Hi, experts.
I am not very experienced with solman, that is why I need your help. My requirement is to display the latest 100 tickets in worklist, if the query is empty. Right now (as per default), the oldest 100 are displayed. Is there a way to do this? I am using Solman 7.1. If the solution requires programming, which it probably does, it won't be a problem for me. Any kind of hint would be appreciated.
Thanks in advance,
Borys
