Saving chart theme.
Is there a way to save a chart theme? I have default and guppi themes to select from, but cannot seem to see a button to save the current theme for later use. I see this question was asked back in 2011, and the reply indicated that themes can be loaded in as files: https://mail.gnome.org/archives/gnumeric-list/2011-May/msg00005.html, but I cannot seem to find any more information regarding this matter.
