Quotes Group seperate Subtotal Service and Products

I am trying to figure out what it would take to have the ability to get a subtotal of Labor/Product. I can do it via one of two ways as using this Quoting system is new and can change our process.

1 Subtotal of any Product Category within Line Item Groups (Preferred)
2 Product line items totaled and service lines subtotaled with Group Grand Totals at the bottom.
