AU preset manager

I just figured out that AU plugins (which have no their own preset menu/manager) do not see where they store their presets via renoise’s preset manager. See the screen.

Can this be fixed?

p.s. This fuzzplus au plugin here is an example how the plugin itself have the presets menu, presets are visible, but there is nothing if i use renoise preset manager. So there is a problem with using plugins with no preset manager built in.

os x 10.9.5

renoise 3.0.1
