need to disable or delete a named object( a button control) on a HSSF sheet.

[MONJAY (Ctr), EDWARD G]

Is there any way to find a button via poi.  The name region in excel shows to 
be Button 107.  How can I find this button using poi?  Also, once found I 
either need to disable it or delete it.  Is this possible with the 3.8 beta 4 
release?

Thanks,
Ed
