Load Bearing Wall - Staad Pro

How do you model a steel beam framing to the top of a concrete load bearing wall in Staad Pro?

The steel beam is perpendicular to the load bearing wall.

It is easy to do in RSS.

Is there a similar method in Staad Pro?

It looks like you can add nodes to the surface edges that will accept the end of another member.

However, that gives a very odd mesh when read into the analysis model.

There must be a best practices guide somewhere for modeling load bearing walls in Staad Pro.
