The key thing to understand about Send FX is that they are not applied to tracks individually, but to a stereo bus that is the sum of all the tracks that are being sent to that effect.
There is no point in the signal chain where an individual track is being effected separately from other tracks, so there is no way to isolate and access an individual track with its FX (unless you solo it).
If you want individual tracks with their FX - you need to put the FX inline in the signal path - either before the mixer or by using the mixer’s inserts.
