I am New to Parallels and Am after some advice on Packager Installs on OSX

We have a Package that we would Like to deploy to Our Macbooks Via SCCM
The Package Requires a Directory to be Created and a File to be Copied - prior the the Application (I have built The Application and this bit Works Fine) being Installed.
So I created a Package that Runs the Following Command
mkdir -p "/Library/Application Support/OpenDNS Roaming Client/"
This Package Works If I deploy It Independently
I then Have a Second Package Which Runs This Command
cp OrgInfo.plist "/Library/Application Support/OpenDNS Roaming Client/"
Again this works fine providing the 1st Package/Command is Run
What I wanted to do was Have a Job that runs one 1st before the Other
With a Windows Deployment I would either use the "Run another Program 1st" option form the Advanced Tab of the 2nd Package.
But doing this for an OSX deployment seems to fail
So then I looked at doing it Via an OSX Task Sequence
But When I Create an OSX Task Sequence and then Add/Edit the Install Package Option - though I can "Browse" to the Package and Select it - The "Program field remains empty and I cannot select a Program to run in the Task Sequence.

Can anyone Point me in the correct direction to Achieve this please?

 

Martin,
"Run another Program 1st" is not supported currently.
I can suggest using a non-OSD Task Sequence with 2 steps installing your packages one after another.
