CST - add more than one simulation projects in DS tasks

hi,

I'm using CST Studio Suite   for shielding effectiveness analysis. there is an example in component library " shielding effectivity of metallic enclosure" where per explaination that the SE can only be post processed from the schematic. and SE-calcuation involved at least two simulation models. My question is how to import models under the "tasks"?

is there any good tutorial to show the workflow?
