Change pitch of roofless rafters (patio cover)

[kraftwerx]

I probably went the long way around to create this, but was able to create a roof plane detached from my house, then build the framing and remove the roof. I've been tweaking and adjusting the "block" that I will use for my wrap around patio covers when I realized I goofed on the pitch and had a 1 in 12 inches vs 1" in 12ft. For the life of me now, I can't change the pitch of the rafters.

Is there any way to achieve this without having to revert and start over? Also, I'd really like to make this an architectural block but when I select the framing members, I don't get the option. Is this possible?

Thanks in advance, Erik
