Beamforming configuration

Hi,

Re:https://wiki.seeedstudio.com/ReSpeaker_Mic_Array/

Can anyone confirm if both the 4 and 7 mic array have beam-forming? (I see the 7 array does support it).
Also is the beamforming configurable to let’s say … someone standing just by one of the microphones. Ie. half a metre from the microphone at the 6 o’clock position.

Thanks
