Feature Request

I wanted to request a feature;
 
+  Add a function that will permit opening the current image in an editor of the user's choice.
 
One of the features I have seen photographers use in Pie Studio is to set, in preferences, an editor such as photoshop, Gimp, Elements, ACDSee, etc, and then hit a function key, or a control key, and that image will open in the editor for more detailed tinkering/evaluation.
Does FRV already have this feature?

Thanks,
