Logic Pro X How to get Folder automation to apply to contents

#1
How can I replace the snare drum from a live recording? It was separately mixed. i moved the EQ low pass filter up to around 200 Hz and can get rid of much of the bass drum sound. Perhaps with a noise gate I could isolate it pretty well. So after that, how can I get a snare sound I like to be triggered by it?
Do I send the output to a buss? Then what?
TIA
