wxCodeGen - support for propgrids and fnb's?

With wxFormBuilder 3.0 you can use plugins, one of which adds support for property grids & flatnotebooks (among others, see wxAdditions).

Any chance of an update for wxCodeGen?

EDIT: If anyone else is using the plugin, you can put buttons in place of a FlatNoteBook or PropertyGrid and easily swap them out later in the generated code.
