Selectables: How to prevent unselect from occurring?


Hi
I'm using the jQuery UI Selectables library, and so far so good - it's
easily taking care of all the things I'd like to do.
Though what I'd like is for the user to make their selection with a
number of drags if they choose to.
I was wondering if people have recommendations on the best way of
preventing previously selected items from becoming 'unselected' when a
new selection is made. I could attach my own events, or modify the
callbacks, or try to comment out the lines from the Selectable
library, but is there a preferred 'clean' way?
Thanks
Luke
