Would make Trigger definition quite faster and more powerful.

This could be auto-added to the 'Activate, Disable, Mass update, Copy selected to, Delete' bottom left dropdown list.

Idea would be to auto-generate a dialog box showing all selected Triggers
asking which logical operation(AND, OR, XOR) to apply on them (default could be the AND operator)

Should ideally have an 'At least X activated' extra option,
where we could for eg. setup a combined Trigger with the following characteristics:

• 4 related Triggers
• will only activate if at least 2 of the them are ON

(the php code would only get an extra check to get a count on the total activated triggers id in it)
