Changing the simulation temp from a task

Teeeravis
I would like to change the simulation voltage/temperature in an AMS sim from a task

general setup below
 
I want the simulation to go through a bunch of states,
reach a steady state,
start a task that fires off changes in the temp/voltage
ramp temp
measure stuff
repeat  
 
something like
cds_globals.xtemp = 50;
cds_globals.supply_voltage = 1.5;
where xtemp is variable that drives the temp in the ade-l gui.
 
I tried this, doesnt work, cryptic debug messages dont really help me on why.  
 
I've seen the following commands and think these may be useful but honestly im kinda grasping at straws.
 
$temperature  <- reports the current sim temp  (didnt seem to compile)
cds_globals.xtemp = 50;  xtemp is a parameter in the cds_globals, compiler complains that you cant assign values to these params
amsDirect.simcntl sctemp string "temperature" (saw this in the manual, not sure you can fire this command from a task)
 
I'm not looking for the dynamic parameter solution.

Any help would be appreciated

    You can't do this. Dynamic parameters are the only way right now. One thought I had was that you might be able to stop the simulation and use the tcl command to change analog options, but I don't think temperature is one of the things you can change, and then run a little longer. However I don't think that's any more advantageous than the existing dynamic parameter approach (assuming it is possible, I didn't check as I'm offline)

    So contact customer support; this would be an enhancement request.
