Multi-orbital cube files

Dear All,

I am using Avogadro for a while, and its ability of rendering cube
files is really good.
However, I’d like to display multiple orbitals of same molecule, one
orbital function
a time. I have tried to search the file format of multi-orbital cube
format on the web,
but there’s no explaination about it. May I ask here what is the
specifications of
multi-orbital cube file format that Avogadro can work with? Thank you.
