Increase epic capacity to 1000 in workflow board

I manage a large portfolio for a product offering that is made up of several workspaces. I have an epic workflow board where i bring everyone together to get status and move epics across status columns in our workflow board. We recently went over 500 epics and I'm now receiving the following error: "More than 500 epics have been requested so the data has been truncated. Consider using a filter to reduce the number of epics being displayed."
