Inventory movement

I'm using MAS 200.  I'm looking for a simple way to check inventory movement, ie how many of a certain inventory item have we sold and/or issued in a period of time.  I know that I can run inventory sales history reports and inventory issue history reports, but I don't find a way to choose a date "range" and have a total number.  The report shows the inventory by period and doesn't give you a total.  So right now, if I want to know how many widgets I used in the last 6 months, I have to print both reports, then add together the 6 periods in each report.  Does anybody know of a better way to accomplish this?
