How to use a specific data set in ADS?

Hi, I want to use a specific set of data that I generated anywhere else, as input to an amplifier in ADS. Can I put a box and load a file with that data in it like I do while working with S parameters? Or I can put a user defined voltage source if any. I searched a little bit and saw that I can use user defined voltage source but it needs .ds dataset file which is created in ADS. I couldn't figure out how to put a set of voltage data which is not created in ADS and use it, how its format will be. Does anyone have an idea about that? Thanks in advance

I can't understand meaning of your questions.
