Sccm OSD - how to set Scanstatestore as ComputerName

[pldpld shalom]

I'm trying to build ZTI with SCCM.
I Build the all Packages and system (CustomSettings, MDT, USMT and
BddadminDB).
I dont know how to set the proccess that it will backup with USMT to network
share and backup data to specific folder with %computerName% name.
Whene I set ScanStateStore to the share and use UDDIR=%computername% the
proccess ignor frome the UDDIR ver and backup straete to the ScanStateStore.
Whene i use Scan StateStore=\\serever\share\%computername% the proccess set
the right command line for the usmt (i can see ut in the logs) but before it
run the command, it try to connect to the folder - the folder is doesnot
exist yet (the share exist but the folder name as the computer name shuold be
craete buy the usmt command line), and then the proccess fialed.
Anyone know how to do it?
Thanks,
