In one aspect, a method is for use in connection with a content-modification system that includes a content-distribution system and a content-presentation device. The method includes (i) identifying an upcoming content modification opportunity on an identified channel, wherein the identifying is based on detecting a match between first reference fingerprint data representing an initial portion of a first modifiable content-segment and query fingerprint data representing content transmitted by the content-distribution system to the content-presentation device; and (ii) responsively: (a) using the first reference fingerprint data as a basis to select second reference fingerprint data representing more than an initial portion of a second modifiable content-segment, and (b) transmitting to the content-presentation device, third reference fingerprint data representing more than the initial portion of the first modifiable content-segment and the second reference fingerprint data, to facilitate the content-presentation device to, at a later time, perform an action.
