Setting window properties on native dialogs

[jwbst21]

How can I set window properties on grid native dialogs like configure grouping or configure sort? I tried something like

isc.MultiGroupDialog.setProperty("showModalMask, true)

, but this is not displaying the mask when the dialog opens. It is modal, I just want to display the mask to be consistent with my custom dialogs and also other grid native ones like edit hilites.

That API doesn't really exist (or at any rate, it's not a static API), but setDefaultProperties() would do what you want.
