Display results from multiple buffer/select feature tasks

I have a workflow that performs 3 buffer tasks, and then selects the results from each one.  However when I run the workflow, the first two sets of results show up briefly, then are over-written by the final buffer/select task, leaving me with only 1 set of results.  I would like to have all 3 feature sets returned in their own separate tab.

I found a suggestion of using a 'RunExternalCommand' with the command name "SetActiveFeatureSetId" and the command parameter left null, but this seems to have no effect.

Working in GE 4.3 and HTML5 2.4
