You could have a property inside the controler to select the proper theme value
with a fallback, your theme singleton would then need to have different set of
property var defaultTheme: panelTheme
property var mainTheme: ...
property var panelTheme: ...
if(prop && component.hasOwnProperty(prop))
// use style with default theme
// Button with theme color
property string customTheme: 'mainTheme'
As for loading a multiple different template I think it would be impossible.

different set of colors for a Dialog. Any suggestions on how to
