The checked box causes the label to place individual
taps instead of the unitary bus label put to the Name(s)
field.
You might be able to give it a space delimited line of
names, which you could paste from some intermediate
text file, buffer, etc without needing the Expand option,
I know it will deal with space delimited regular names.
Now there's likely to be some issues with < and > in
SPICE netlist evaluation, and you might want to work
out a "safe conversion" for those (if you mean to use
standard bus style) that a script-duo can reliably turn
to and from SPICE-digestible, "special" but not often
used nor especially "active" proxy characters so the
netlist can be run after it all, not erroring out over
"malformed math" that was really just dialect clash.
