it is possible to modify several similar objects at once?

[#1]

Hello,
I want to know if it is possible to modify several similar objects at once?
For example, I have an identical car icon several times in my illustration. I want to add a wheel to the first one and have this change happen automatically on all other identical car icons. Is it possible?

Using symbol instances would be one way.

Another way would be using the Global Edit feature.
