Is there a way to prevent the spacer coming off when swapping grinding wheels?

As per the subject, is there some neat trick I can apply to prevent the spacer to come off when I swap between grinding wheels?

Not really. It does tend to stick to the wheel when you take it off.

Yeah, annoying. When I remember to, which is often not, I move the wheel out enough to reach in and touch the spacer to separate it from the wheel and then finish removing the wheel.
