[NTG-context] Is there any intuitive way of handling missing characters?

Dear List, Is there any way to give a sequence of fonts to context and let it try one after another in case of missing characters? Ideally it should be something like \usefallback[font1,font2,font3,...] The methods I've found are all way too complicated for someone who does not really care about fine-grained control over unicode coverage or customizing a typeface with different serif/sans/math/... combinations from different typefaces. Thanks! Best, Sylvain
