If I create an autodiscovery template, with no triggers, and decide after the template has already been applied to a host and has discovered items, that I want to add triggers, the triggers do not get applied to the hosts.

For example:

Network Switch Port Discovery Template created and applied to a host.

The discovery process runs, creating the items on the host.

The I decide that I want some triggers tied to those items, so I create some triggers in the template. The auto discovery process does not add those triggers to the host. I have to remove and clear the template from the host and then I need to reapply the template onto the host for everything to get reapplied to the host.
