automatically install software in a sequence without using delay custom properties

HI,

I am having a 6.0 setup.

I am doing a Windows server provisioning using a guest agent and then installing a sw on it.

i am also using custom properties to specify the list of sw to be installed on the guest os.

however, i have to use the "VirtualMachine.Software1.PostInstallDelay" to wait until the software gets installed.

can this be automatic or is there any other optimal alternative?

What i am looking for is - after the software1 installation starts, it should wait until the software installation is complete and then move to the software2 installation all automated without me having to specify a custom property like PostInstallDelay

Thanks.
