Animation of a frame to show MUs

[NIROE]

Hello community, 

I want to implement a frame "test" (see attached screenshot) in my simulation model. The frame "test" includes a conveyor. In the end, my goal is to show the MUs also on the symbol of the frame "test". In other word, I want to animate the frame "test" without showing the object "conveyor".

Does anybody have an idea, if there is an option to animate only MUs on a frame symbol? 

Thanks in advance !

basically: create a animation line in the icon of the frame and link the animation line with the conveyor

That was easy! Thank you
