Rotate image template

I made a conveyor in a template.
Inserted the template into a window.
I inserted a square into a window also.
I can rotate the square, and the symbol factory stuff inside the window.
I can rotate the conveyor within the template window.

How do I rotate the conveyor template I added to the window?
The rotation buttons are disabled for this.

Templates cannot be rotated. However, objects inside templates can be rotated. You need to apply the rotating to components inside the template.

You can only rotate components that have a rotation property or angle property.
