Macro Mouse Position

Hello, so for me it's also important to get a mouse position function, the recording is fun but honestly little annoying. It records the movement from A to B, but what I want is to set an absolute mouse position on the monitor, so for example I could set it to 600x300 meaning 600px on the width from the left... and 300px from the top. I need this because when for example I'm selling items and my equipment has like 300 items i can like hold a macro and it would delete the item instantly. Short said a macro that inserts mouse coordinates so there is no need of recording but just simply set a absolute mouse position on the screen.
