Creating relations/derivitives from one seperate part to another?

G'day all. I want to know if there is a way to link sketches and/or features from one part to another so that any changes done to the related features/sketches in the parent are reflected in the others.

I have a profile cut steel plate that has a doubler plate on each side which both share certain profiles with the main plate. I would like to be able to make changes to the main plate and have this reflected in the doubler plates.

Thanks

Chris
