Design Review Slides with modified engineering connections

Hello everybody

 

From  time to time we get the question from different customers to be able to see products in different positions on the drawing and in 3D. Something like an open and closed door of the same product. Since until now it is not supported to do that with engineering connections (they are excluded from the supported properties that can be overlaid on a slide) we wanted to ask how you guys get around this? We know that it is possible using the robot or the manipulate mode but this seems way to slow and/or inaccurate in respect to the capabilitites of parameters in combination with engineering connections. What is your best practice for this usecase?
