Somewhat repeating gfretwell - ground wires can be doubled up but only
if the label indicates that is permitted.

Neutrals may NOT be doubled up - NEC 408.41

In a service panel you can add a ground bar which the label indicates is
acceptable and move ground wires to it. In a subpanel that doesn't help.

ONLY IF YOU KNOW WHAT YOU ARE DOING - you could take a neutral from an
A-leg circuit and a neutral from a B-leg circuit, wirenut them together
with a single wire to the neutral bar. It is easy to do this wrong.

researched say yes, others say no. If no, what are the options
