Slice One BIG photo into many small photos at once?

[arma]

Hello,

Is this possible to slice many small photos at once? Multi crop?
I have very big size photo, and i need to slice into many photo... If i do repeat -crop x1 y1 x2 y2... it takes long time. Because of photo size. I wonder if multiple crop possible at once?

Thank you.
