Can WW3 be run on nested grids for coupling?

Hi everyone,
I would like to run a nested ocean-wave coupled simulation. I managed to run croco(v2.0.0) coupled with ww3(v6.07) on the parent grid and uncoupled on the child grids, but I don’t know how to run a nesting in ww3 to match the croco nesting.
The ww3 v6.07 manual says running OASIS and ww3_multi is unsupported, so it might not be possible with my current setup.
Does anyone have experience with wave coupling in nested setups?
Thanks in advance,
Ron
