Entity walking control

Hello! I have a request, is it possible to add an opportunity in the procedure that will allow you to control the walking of the entity? For example: if... do: entity walk from (x y z) to (x2 y2 z2), or blocks like: take 5 steps right (left, forward, back)

Also, I really want to add more flexible GUI settings, the ability to add custom buttons with your own images, etc.
