Display filters only operate on the information in a single frame, to decide whether that frame should be displayed or not, as such they can't create "associations" between frames.

Some protocols include references to other frames in their data, e.g. "this is a response to request in frame xxx" that can be used in display filters, but I don't think that's relevant for your case.

Maybe you could try a filter that selects frames by the bigger length length or the short length and the time delta to the previously displayed packet, e.g.

(frame.len == 118) || ((frame.len == 97) && (frame.time_delta_displayed < 0.02))

Depending on the timings, this might still display frames with length 97 that aren't related to the 118 frame but do occur less than 0.02s after another length 97 frame.
