I hope someone can give some suggestions for this. I've done quite a
bit of searching and am having a hard time finding anything online to
suggest the best way to patch aggregate.

My situation: I have an old aggregate concrete patio that a wooden
porch was built INTO. Recently I tore out some boards on the porch,
including 2 that were sunk down into the concrete. They pulled up out
of the concrete very cleanly, but left 2 holes apprx 2x6 size in the
patio. I'm looking for a way to fill the holes to match the rest of
the patio...dont just want to do plain grey concrete. Suggestions on
the best way to do this? Is it going to be tough to match the top
level of the existing patio? Is there some pre-mixed aggregate out
there I could fill it in with and be done?

I'm a novice when it comes to concrete so go easy on me. Thanks!
