Nope, tell a human to do that for you.
Simple, Set up a video feed (Fid? idk) Now Go set up ur mouse so that it can be clicked by an item that is big enough make sure the pointer is allready pointed at the ready button set up a timer where something can click the left click this way teh cow will be ready its easy as that
Bottom line is, make an item that can auto click the mouse while its allready pointed at the ready button set it up for 30 secs this way while u go up it will be ready then just hold that thing down so the cow will shoot and it wont get kicked its easy science =D
