No currently not, the 09xx are static pattern data and they aren’t dynamic processable, well at least not realtime. (you can do a lot with scripting but for real-time intervention and action, the scipting engine runs in the wrong thread:The GUI thread)
IT-Alien once created a script to change loop-markers assigned to Midi controls:

It could perhaps be adjusted to set slices and then you can add a few 09xx commands fixed in the pattern, simply change the slice position of the sample slice attached to the programmed 9xx positions before the 9xx command is applied (i think this can be done because you can buffer actions without worrying about real-time intervention).
You have a problem if you have multilayered samples though, because you loose the existing layers when using the slicer.
