FX and Bus can be assigned to CUE, once you checked the option here:
then their CUE mix will appear
If you want to BUS some tracks for seperate CUE for artist, you need create a BUS, then manully sending tracks to it. then switch those sendings pre-fader mode. remenber to close the CUE on these tracks otherwise you will get 2 pairs to CUE(tracks to CUE and BUS to CUE).
Now the tracks maintain the original mix to MAIN, also their signals will send to the BUS, then BUS could control the CUE volume by slider. notice that BUS to MAIN should be closed(Nothing should be added to MAIN otherwise your original mix will be mess out)
FX channel could be done by same method. One track need FX to CUE, you just prefader sending it to FX, and change CUE value by slider, then artist should hear his own FX mix.
You can also create a special FX for artist only, by routing it to the BUS, let BUS do the CUE mix.
There are many other ways to do the routing trick, that's what I would do in this case.and its fun, I'm shorts of language so sorry for my poor explaination, wish this will help!
