How do I make this vertical structural member flush with the other two members?

Hello everyone,

I'm trying to make a frame using 1" x 1" and 3" x 1" members in Weldments. My first attached picture shows my 3D sketch, while the 2nd picture shows the result of adding my structural members (along with a Tim/Extend feature.) Because of the 3" x 1" member, the vertical member is 1" away from the edge of the two structures. What I want is to have the vertical member flush with the other two members. I know I could achieve this by manipulating the 3D sketch, but is there a simpler and/or more robust method of achieving this?
