CitcomS restart with new temperature anomalies

Dear CitcomS Users,

I am running some time dependent models using CitcomS. My input includes temperature files as well as tracer files for viscosity. I am interested in restarting the models keeping the tracer viscosity from the last step but incorporating new temperature anomalies (for example introducing a new plume). Restarting the run using the checkpoint files, makes the program read in temperature and viscosity information from the last step. If I want the program to read in new temperature files, the previous viscosity information is lost. Does anybody have a suggestion about how to resolve this?
