Yes, just use the
name key for the term and the
symbol key for the symbol. See Gallery: Units (glossaries.sty) for an example. If you want the symbol to also appear in the text when you use commands such as
\gls, then you can redefine
\glsentryfmt or use
\defglsentryfmt (those two commands are new to version 4.0).
With glossaries-extra, it’s possible to use the post-link hook to automatically append the symbol, which is simpler than redefining
\glsentryfmt. See Gallery: Units (glossaries-extra.sty) for an example.
