Put a product on a till hot key from Isletek

A product with no barcode, such as a sushi tray or loose goods, is rung up from a hot key on the till. Today that hot key is set up in Semtek by hand.
From Isletek, when a product is added (Add to POS, Create product) or from its product card, you would choose the hot key page and the button, give it a caption, and the till would show it after Update Till.
