You can perhaps use "App\System Tools\Portable Finder CMD" but the AutoRun shortcut Inside (Add_Shortcut,AutoRun) is may be started too early to map your Network drive.
You can also create your own script to copy your bach file, create a shortcut (MacroLibrary/Add_Shortcut) and launch it via Autorun.cmd
If,ExistFile,"%target_sys%\autorun.cmd",Begin
TXTDelLine,%target_sys%\autorun.cmd,exit
TXTAddLine,%target_sys%\autorun.cmd,"start blablabla",Append
TXTAddLine,%target_sys%\autorun.cmd,exit,Append
End
To add a pause and wait for the network if needed. Galapo's Sleep.exe is included in the build
