Used VBA to do the heavy lifting
In essence, the template has a stencil that has the dashboard and some specialized shapes. You drop the animation shape on the static shape. You trace the animation shape path (move, right click, add step). When you run the animation from the dashboard, the VBA moves the animation shape along the path you defined.
There are straight/arced paths, show/hide shape, add/delete steps, etc to select from. If you want to move the static shape with the animation, add it to the group of the animation shape so the whole thing moves.
I have been thinking (have not had much time to try it out) of using the points function in VBA to have
the animation shape follow the static shape path. Aka the other way around from adding the static
shape to the animation shape (no need to trace path with steps).
The animation uses the timer function in VBA. Crude but sufficient.
Obviously, if you look at the VBA, you can tell I am not a programmer per se (actually an engineer) so
I am sure there are slicker ways to code this up. The rest of the VBA is there to make all this come together (each animation shape holds its own path, determine which shapes are animation shapes, etc).
Feel free to play around with it (add to it or pull out what you need). Be sure that if you add to it, post
it up here for others to use/enhance. I do think you need this to be a template so the VBA stays with it (take your static diagram and copy / paste into template then add animation....or....create your static diagram in the template to begin with).
good luck.
