Currently triggers which are created from trigger prototypes are read only - there is no possibility to change the trigger tags or other properties directly, the only possibility is through modifying trigger prototype.

On the other hand we have trigger tag based maintenance, where only problems which have specific tags can be suppressed. 

When multiple triggers are created from prototypes, it is hard to create unique tags for each trigger. 

It is suggested to resolve the Zabbix built in macro {TRIGGER.ID} in the trigger tag value field, which will open possibility to mark each problem created from that trigger with unique tag containing trigger id. This can be later used to suppress specific problems in maintenance.

The macro in tag value field must be resolved in triggers which are created manually, and in triggers which are created from trigger prototypes.

There may be other use cases for this functionality as well.
