Setting to NOT delete empty changelist when 'active' state changes to 'non-active' Follow

I currently have PivotalTracker integrated in IntelliJ and I often work on multiple bugs at the same time.

1) I open a PivotalTracker task and that automatically creates an active changelist
2) Upon committing my changes, this active changelist is now empty
3) As soon as I work on a different bug and open that new task, another active changelist gets created thus switching the currently active changelist

The problem/feature is that now my previous active emtpy changelist then gets automatically deleted.
If I still have work to do on that task, IntelliJ won't recreate a changelist for me when I reopen what is now a 'closed' task.

Is there a setting where I can set it to NOT automatically delete empty changelists when they go from an active to non active state?

Thanks,
