Selectiong multiple Beam (Countour plates, ...) (TEKLA Live link

I use TEKLA 2017 Live link plugin.

Could any of you suggest how is it possible to select and store multiple objects ( beams, contour plates, …ect) in the appropriate TEKLA containers (beam, plate …etc) ?

It seams that I can select and store only one element in one TEKLA container, and this makes the forkflow relatively difficult.

Many thanks in advance!
