NAT in CISCO 4500x


We recently bought CISCO4500X Switches and planning to configure them as core switches. Unfortunately, these swithces are not supporting NAT. 

Here is the sh version result. Is this because of hardware limitation or IOS ?. Will it be resolved if we upgrade the license ?. if yes, What license.. Any suggestion ?. Please.!
