Hi Rohan,
Sorry but I wasn't clear. I already do follow these instructions. The list of Lenovo laptops in my original post are already in our hardware customized package.
My point is that it is really unacceptable to add new models using the steps in the link you shared above.
Here are my problems:
1) No button to edit an existing model. You need to delete the model, and add it again, with the different settings.
2) No way to import a list of models
3) Not possible to add models with a wildcard, for example "LENOVO 4236*", instead each model number must be entered one row at a time.
This is ridiculous that the means to manage an "enterprise" level product is so primitive.
I've open a ticket with Symantec Support.
