Probably the easiest way is to use Qsys (File->New Component) and then from the component editor use the Templates menu to add the type of instruction you would like to add. For what it's worth, I personally like editing the TCL manually, so I would just get the tool to generate the first round of port definitions and then copy&paste that into my own .tcl file. (I have had trouble with the Component Editor in the past, and I do not like it).
