change text in submenuitems before it is shown


I use the WebMainMenu and it looks as follows:

MenuItem1      MenuItem2                    MenuItem3
               - SubMenu2ItemA
               - SubMenu2ItemB 
               - SubMenu2ItemC

Now I like to change the text "SubMenu2ItemB" befor it is shown when I hover over the MenuItem2 element

In the object Inspector I found for the MenuItem2 only the Event OnClick?
But without a click I'm not able to change the text an when i hover over the menuItem2 the old text will be showed.
What can I do or which settings are neccessary solve my problem?

thanks a lot

There is at this moment no menu item hover (like in VCL), so unfortunately, at this moment, this isn't possible.
