Can we use the same sphero first responder

Can we use the same sphero first responder to knock of each of the people or do they need to be different first responders?

@HPT1-Row_Dyer sorry for the late response here. Per 5.1 [Phase 2] of the Game Manual:

You will NOT receive points for the following action: Two (2) Sphero First Responder(s) landing and unloading on remaining Residential Buildings

You WILL receive points for the following action: “Stranded People launching off the Fire Escape Platform”
