about a model

i wanna a model that contain sphere with dipole and ellipsoid without dipole,how do i use the command"atom style"?
Can i write this "atom_style hybrid dipole sphere ellipsoid " ?
Because i have to use the “fix nve/sphere update dipole” to describe sphere with dipole.
But for “hybrid”,when you set the arguments of each atom,you have to list them as follows “atom-ID atom-type x y z sub-style1 sub-style2…”.
So i just donnot how to set the args,if i have to use “fix nve/sphere update dipole” to update the dipole set onto sphere within a system which is a mixture of sphere with dipole and ellipsoid without dipole.

​you have to provide all properties for all atoms, even if they are not
used by the individual pair style or fix.
in your particular case, the *real* worrying question is: how are you going
to describe the interactions between the spheres and the ellipsoids?
the only consistent solution that i can imagine would be to model all
particles as ellipsoids, as a sphere is just a special case of an
ellipsoid.​ same for the dipole, you can just make the dipole vector
(0,0,0) for particles without dipole.
