Hey Christen,
I was thinking along the lines of creating an uplift value on a rafter to wall top plate connection and prompt a simpson hanger drop down menu similar to selecting a floor joist to flush beam connection. (H1, H2, H2.5, etc) I hope I’m explaining that correctly?

Currently, we determine the wind pressure using the simplified version, but only apply this as a lateral load on headers and wall members, we do not apply this as a upward force on a roof joist. We currently rely on the user to input the wind load on the rafter. Are you asking for us to utilize the same procedure used for wall members but apply it as a upward load on a roof joist cantilever?
I believe this would really depend on your wind analysis of the entire building, and not just the rafters in isolation. Depending on if you're using MWFRS or the simplified version, and what your external/internal wind pressures and resulting uplift.
