RibbonCustomizeManager - delete actions

Hello,
in my application, the user has the possibility to create own actions that can be added in the ribbon bar.
I'm able to create the actions, add/delete them in the ribbon bar and add them in the customizeManager dialog.
But the user can also decide to delete them and I don't find a method in the CustomizeManager class to delete an action added in a custom category.

Can you help me?

We will add the function in comming release QtitanRibbon 4.16.
void RibbonCustomizeManager::removeFromCategory(const QString& category, QAction* act);
