If you wish to use these partial factors in CAESAR II put the 0.67 in the piping inpu screen as the System Design Factor. Then, in the Load Case Options, confirm the proper multipliers are listed for the "Occasional Load Factor":
SUS=1
OPE=1.24
OCC=1.33
These numbers are multipliers of the System Design Factor.
You may have to update these if you modify your load cases.
(You say "SUS+T", I say "OPE" but I think we are saying the same thing.
