[Feature?] Preventing comfy from running the same "group of queue requests"?

### Feature Idea

Right now comfy will not re run a request if the same request has just run previousely, but if you run a request from earlier then comfy will run it. for example:
prompt1,prompt2, prompt1
you will get 3 generations, but:
p1, p2, p2 => the second prompt2 will not be run, comfy just skips it I suppose

What I WANT (does it exist already?) is to find a way to make comfy ignore groupe of requests, so for example:
(Request1, request2, request3), request4, (Request1, request2, request3):
Instead of having 7 generations we would get only 4 because the group (Request1, request2, request3) will not run again and would be detected as already treated.

Can we do that?
