How can I give a new patern ?

Hello,
I had to draw a new partern to figurate a stone-made wall (drawing a house for a client) : I called it "Meulière" (witch is a French-term to call it ...) and it works fine.
Is it possible to give it to be added to the proposed hatching paterns ?
How ?
Thanks for your attention.
