Can we change the options for turning on/off the noise contributors in the simulation script?

I would like to turn on/off the noise contributors and then run the various noise analysis. Something as shown below. Is this supposed to work? The second options statement doesn't seem to take effect.

Thanks!

thermaloptions options psfversion="1.1.0" reltol=1e-3 vabstol=1e-6 \\
iabstol=1e-12 temp=25 tnom=27 noiseon_type=\[thermal\] scalem=1.0

noiThnhv ( vgsn_io 0 ) noise values = \[1k\]

//Flicker
flickeroptions options psfversion="1.1.0" reltol=1e-3 vabstol=1e-6 \\
iabstol=1e-12 temp=25 tnom=27 noiseon_type=\[flicker\] scalem=1.0

noiFlnhv ( vgsn_io 0 ) noise values=\[1k 10k\]
