Install updates during post install

Good Morning,
I'm not sure if anybody out there is using Kace to push scripted installs to workstations or not, but here is what I am trying to do.
During a post install task call a script that will utilize the downloaded updates from wsusoffline and then install them. I know you can pack them as an .iso but not sure how to script then into an install.
Any help in this direction would be much appreciated.
Thank you
Patrick
