Proposal Grouping

I would like to be able to display each item in my estimate on the proposal. This is easy enough.

However, I would like to group some items like framing.

Ideally in my estimate I put in every framing item I need, plates, joists, sheathing, studs, etc.

Instead of listing all of those items in the proposal I want to only show the groups for those, ie Framing Materials

So if we can pick and choose to have certain groups only show as the summary, and other groups show each item that would be preferred, so we can build our estimate to the tiniest details, but only show the work in tiny details to the client, not every material part.
