Yes. That works great! Thanks again!

Since I'm wanting to be able to use this multiple times, for various lists, I end up with:

AdjectiveNoun(Adj, Noun)=>
  let combo=[];
  for(const a of Adj.selectAll) {
    for(const n of Noun.selectAll) {
      combo.push([a,n].join(' '));
    };
  };
  return [joinlists(combo).consumableList];
