List of Used or Queried Account ID in Windsor.ai#1359

So basically, I need to know how many advertiser IDs or account IDs are being used in windsor.ai query (bigquery, looker, google sheets, etc.)

Later, I can remove advertiser ID and account ID that are not being queried from the “Selected Accounts”

A table consists of Advertiser or Account ID and Data Source that are being used in windsor.ai query would be very helpful, if you can give me it within a feature. Thanks so much.
