Ali Rafiee gave more information on the question:
Hello Jan,

in below simple example you can see my question in the model.
I tried to have all of possible cases.

I created my interactions before O.engines by createInteraction command,
and I suppose this command works for this type of interaction creation.

thanks a lot
Ali
