Disable a check box from Account Code Combinations form for specific Accounts

Hello All,

I would like to find out if any of you have any ideas on how to trigger an event when there is an update on a specific account code combinations form eg.111-222-2345 is enabled it has to notify Finance that update or undo the update or disable the option to update for specific set of accounts. I have tried form personalization to disable the option and was not successful. It disables for all or none. Any ideas will be greatly appreciated.

Thanks in advance.
