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];
