[Microstation Connect Edition 10.12.00.40] Ribbon State: Tabs

Hello there,

I've got a question about the Ribbon State.

When I make a Ribbon Item invisible, this setting will be stored and remembered in my next Microstation session. (The setting is
written in the xml-file that MS_RIBBONPREFS refers to.) This works fine for Ribbon Groups and Ribbon Buttons. However, Ribbon Tabs that I make invisible, will be visible again in the next Microstation session.
Is there a way to make Microstation remember which Ribbon Tabs I've made invisible?

Any help would be highly appreciated...
