Sidechaining Input Filtering

Hi all,
the new sidechaining workflow is great.
I have only one wish:
the posiblitiy to filter the sidechain input to decide which frequency range I will use to trigger the sidechain.
Useful when you use foe example a drumloop and want only the bass drum as the sidechain input.
Here is an example how it works in Ableton Live:

Don’t s’pose anyone worked out if this could actyually be done yet? i’m guessing not and we’re having to wait for some of the dynamics to get an input filter added like Ableton has?
