You'll need to create an AnnotationScheme for instruments. Here's a sample - you'll need to change it per your environment. You need an AnnotationStyle and Filter to go along with it.
<ComponentScheme Name="InstrumentTag" AnnotationStyle="InstrumentBubble" Enabled="true" Tag="XX" Alignment="FlatHorizontal" LeaderStyle="AlwaysNonArrowed" Filter="TaggedInstrument" Fields="InstrumentTagAnno" />
You may can add these via the GUI as well, put I don't use it so can't advise how.
