DM Job From Business Rule Initiated by Button Locks System Until DM Finished

For context, we have a button on a dashboard that triggers a function held in the workspace assemblies (specifically as Dashboard Extender).  That function starts a data management sequence.  When the user presses the button OS just stops.  You can't check status, you can't navigate anywhere else in the instance.  The button remains depressed seizing hold of your instance until the DM sequence is complete. The issue is this sequence takes up to 30 minutes to complete.  You can open a new instance and move on, but that is highly inconvenient.  Is there a way to set it up in the assembly dashboard extender that the DM sequence runs as a background job, and the button doesn't need to stay active until complete?

Thanks,
