Is it possible to mass delete information from a form instead of doing it one by one?

 

I tried to reimport something hoping that the duplicate catcher would notice it and it did not, so now I have three sets of the same information.  Only one set is the one I want.  I would love to be able to either mass remove an import or checkmark all the items on a list that I don't want at once and delete in one swoop instead of one by one.
