Being able to product groups as permenant options

It would be exceptionally useful for users to be able to create product groups and then be able to search for them within the CRM. We could have another filter in the quote line drop down box, for 'Product Groups' - please see screenshot. 

Typically businesses who want to 'group' products will want to do this regularly and the fact you have manually group products repeatedly is a bit of a chore. If you could title product groups and then search for them it would be a huge help. A little further down the line you could configure product groups to upsell with certain items. Such as a group of light bulb variants being configured to upsell with a certain lamp shade.
