Grouping Commodities within IFS for Tracking on Spend

I am looking for a way to group inventory items within IFS to do better reporting for their spend.  For example.  I have 10 codes for gloves.  Is there a way to add a code for Gloves that could then be used for reporting to quickly review spend by category? If i have several categories, example, Gloves, Glasses, Abrasives, etc.  Then I could run a report to see what all falls into each bucket; and as these items are requisitioned out, I can run reporting that shows the spend by group and by cost center.  I don’t know where to add that level in the system - and am assuming Pre-posting will be involved - - which for inventory Items we don’t prepost, they just go to inventory, and as they are req’d out, they are then assigned a cost center.
