If it's helpful, I agree with nemainofthewater that nobody would be confused about a request for something like "any SID member." (I should have included Lao Li and Sang Zan in my original comment; I left them off because they're more peripheral members and aren't always included in stories with the "SID Ensemble" tag, so I think leaving them out of a story would also be fine -- but for someone fulfilling a request for "any SID member," they would definitely count!)
