Docked Flyout Toolbar Icon help

I have created a flyout toolbar that I dock but I want a main icon to be the cover icon and not whichever icon within the toolbar that you choose.
Basically I want that main icon to always shows when you have the toolbar docked...even if you choose an icon from within the flyout.
I hope this makes sense.
How do I write this into the menu?
Thanks in advance for the help.

 

To use one bmp for the whole flyout, change the code as follows:

Code:

ID_Tag [_Flyout("FlyoutNameYouChoose",Your16x16.bmp,Your24x24.bmp,_OwnIcon,ACAD.ToolbarReference)]

Now the only thing that you need to reflect in your code from the above code is the _OwnIcon, the rest is whatever you have already. Default for a flyout is _OtherIcon, meaning it switches.
