Support for quantizing activations

Hi, I see that the GPTQModel library supports GPTAQ/GPTQ v2. In the GPTAQ paper, results for configurations such as W8A8, W4A4 are shown. However, I could test only weight quantization with GPTAQ/GPTQ v2 so far with the library. Are there any plans to add support for activation quantization as well? Thanks.
