Yes it is, but I'm not very sure how. From what I see in my registry there
is only a single key named CmdMapping, containing several values associated
by installed extension.
Name Type Value
Default REG_SZ ""
(GUID) REG_DWORD 0x00002000
(GUID) REG_DWORD 0x00002001
(GUID) REG_DWORD 0x00002002
NextId REG_DWORD 0x00002003
>From what they look like it seems are command IDs used by the parent rebar
control (possibly also by IOleCommandTarget ?).
But this is only a guess...
