While you do need the CRM webtool to be able to create timecards for specific clients, you actually need the Commerce webtool.
Since you are a certified AllPro expert, you can add the Commerece webtools for free under Settings->Webtools
Once you've done that, you can create new timecard classifications by creating a new product. Just go to create a new product either through Store->View Products or through the "Add New" menu when you click on the + on the top menu bar.
When you create your product, make sure to choose "hourly" as the product type. Then when you go to your timecard, you can choose between your "hourly" products as your different classifications!
