It is not possible to do it from that report however If you grab one of the PT4 Summary Reports available for free download in the
warehouse, you can add a filter in the blue Filters link for a minimum number of hands - use the blue Insert link to insert the statistic hands, and then add your filter (e.g. #Hands# > 1000) and save it to apply that filter to that report. There are 3 player summary reports there which will give you a good base to work from in replicating that report. Just use the search terms "player summary"
