If you mean ‘apply the new correction to all the shots that it was previously applied to’, it would have been better to link them with some kind of signifier, like a flag, or to have separated them out onto different layers… created a group, those sorts of approaches…
The physical reality of grading a project over the span of the project is that one specific correction is unlikely to take care of every occurrence of a clip or situation, and is, to a certain extent, the dangerous part of linked clips. If you start tweaking at one end, it is more probable that different tweaks will likely be required as the show progresses — it is almost a law of diminishing return that the closer you are to having a uniform grade, the more obvious the small differences will become, necessitating tweaking the tweaks. Its what happens in any grade session. More often if you are charging a flat rate.
