ANSYS HFSS Array Phase Shift

Hello. I have an array of antennas and I would like to model the effect of phase shift between each antenna in the array on the gain pattern and power output. I have looked through the HFSS Help and the best way I have found is to "Edit Sources" and manually change the phase of the port feeding each antenna for every simulation. This is very tedious and I was wondering if there was a way to sweep these phase parameters or some easier way to accomplish this is general.

Thank you!

I am not an expert of antenna but but I wonder if it is possible to define the phase of source as some variable and then use that variable to sweep as this is possible in case of master slave boundary condition in HFSS where we can define the phase delay as variable then sweep it to get the dispersion curve for RF structures.
