Knew it couldn't be THAT simple ;)
I've not tested the following SQL, but these two statements SHOULD be about what you need... you can run it from the Host SQL window or do this via Enterprise Manager or with whatever access you have:
INSERT INTO [dbo].[ModuleControls]
([ModuleDefID]
,[ControlKey]
,[ControlTitle]
,[ControlSrc]
,[IconFile]
,[ControlType]
,[ViewOrder]
,[HelpUrl])
VALUES
(<YOUR CONTROL ID>
,NULL
,NULL
,'Admin/Vendors/DisplayBanners.ascx'
,NULL
,0
,NULL
,NULL)
INSERT INTO [dbo].[ModuleControls]
([ModuleDefID]
,[ControlKey]
,[ControlTitle]
,[ControlSrc]
,[IconFile]
,[ControlType]
,[ViewOrder]
,[HelpUrl])
VALUES
(<YOUR CONTROL ID>
,'Edit'
,'Edit Banners'
,'Admin/Vendors/BannerOptions.ascx'
,NULL
,1
,NULL
,NULL)
