Event handlers for "accessing" ammo boxes?

[disobey 10]

Is there a way to trigger an event handler for when an ammo/weapon box is accessed (via the gear menu option for example)?

I basically want to complete a task when the player accesses a weapon stash, currently I have a trigger over the stash but this doesn't make sense really unless they rearm at the stash.

A much better way would be a command to get the complete content of a ammobox and of cause to add and delete entrys.
