Sente Data Source management

I wonder if anyone can tell me if it is possible to add a favourite data source in Sente to either "Quick Add” or the File>New Search menu item? I have a few sources that are listed in the Z39.50 Data Sources List but it is a real pain to have to scroll down the whole of that long list to find them! :frowning:
Many thanks for any help.
