ncsim and signal labeling

As a former Modelsim user I am looking for a way to label signals in
the wafeworm windows, something like the counterpart of

add_wave -label "A7TDMI:HADDR"

using the tcl command

set id [waveform add ...]

but I cannot find any way for this

Any ideas from insiders?

Thanks

 

HI Andy,
interactively you can do 'Edit text' (available in the context menu in
the signal pane). Internally an expression gets created and shown:
