In the first static analysis where you compute the stresses, you can insert a command under "Static Structural" similar to
inistate,write,1,,,,,s

This will create a file named file.ist in the analysis system directory. From the project page, you can use View-> Files to see the file in the list and find its location. This file has the stress state from static analysis

Then in the next analysis you can insert a command under analysis branch similar to
inistate,read,file,ist,'C:\...\dp0\SYS-2\MECH'

Specify the location of the file.ist in this command. This should apply the stress state as initial condition

See if this helps
