I think the only option you have is to use writefinal in the tran, and then readic (referencing the file you wrote with writefinal) and skipdc=yes on the pss, together with specifying the start time as the end time of the previous tran analysis. There is the ability with tran to save a state, but I don't think (if my memory is correct) the saved state from transient can be used as a recover file for pss.

The other thing to consider is whether you really need such a long tstab. Often people use tstab to reach the settled behaviour of the circuit, whereas the shooting method will do that for you in many cases.

BTW, Turbo does help with harmonic balance (and I think the core shooting), but not the initial transient (yet!).

You should also contact Cadence, preferrably with a good illustration of why you need this (this all helps), to ask for turbo to be extended to the initial transient for PSS.
