I believe you want the texput function:
texput (d_0_psi_3, "\\partial _0 \\psi^3");
=> $$\partial _0 \psi^3$$

There is no way (short of Lisp programming) to do that at the moment.
It would be straightforward to modifiy MSIZE-ATOM (for 1-d output)
and DIMENSION-ATOM (for 2-d output) to inspect atoms for the
properties GRIND and DIMENSION, respectively, which at present
are sought only for operators in expressions.
An alternative which might make less of a mess is to modify
NFORMAT (which massages expressions before output) to
look for a property, say NFORMAT, and branch on that.
At present NFORMAT is just a big list of special cases.
If I had to choose I think I would suggest extending NFORMAT.
I think someone mentioned that.
PS. It turns out there is a way to make an arbitrary string appear
in place of an atom ... This isn't very pretty. For the record:
:lisp (setf (get '$d_0_psi_3 'dissym) (coerce "\\partial _0 \\psi^3" 'list))
=> \partial _0 \psi^3
