How to add an offset load to create a moment in Maxsurf Multiframe

Hi im new to multiframe and im wondering if its possible to apply an offset load to generate a moment.

The above image is a basic example of what im trying to achieve.

ive been reading about the master/slave and joint linking to create a rigid body but this doesnt seem to work unless theres members physically drawn between the offset node and the frame.

Any help would be greatly appreciated

Thanks
