Currently this is very limited. You can use macros in templates - these macros will be expanded when template applied to nodes. This can be useful if you create template and need to pass IP address or node name to parameter after it was applied to node. Here is short description for template macros: https://www.netxms.org/documentation/adminguide/data-collection.html#macros-in-template-items
