Snapshots API failsafe suggestion

Hi, love the snapshot feature, but it’s very strict on symbols param.
i’ve prepared a list of symbols from api.alpaca…/v2/assets
when i call snapshots, i get invalid symbol: IACB (and tens others also).
it’s very costly to call the api to check each symbol before having a valid list to ensure that we get response.
i suggest a failsafe response where the server give a response for valide symbols, and ignore and/or return a list of invalide symbols (those with a problem) or else every call fail because of one symbol and there’s no way to do that

calling snapshots throws an error about IACB not valid, but calling /IACB/snapshot (single symbol) works fine.
