Multiple sync cues in sync opt?

Hi guys, I wonder if there’s a way to express “either one of the following cues is ok” in sync opt, here my code is “both of the cues must be sent to make it start”.

live_loop :drum, sync: [:met, :d] do
  sample :bd_haus
  sleep 2
end

And I know that inside of the code block, I can use sync :a, :b to express “either one of them”, using sync [:a, :b] to express “both of them”. But the previous one can be used in sync opt due to the syntax ambiguity, so how can I do it with sync opt?

Sorry this isn’t possible at this time but is definitely something that would be nice to have.
