A Bishop Problem

From the book "Across the Board" by John Watkins, comes an interesting question about Bishop Tours. Can a Bishop starting on a1 visit each black square along a diagonal only once, before finishing on h8? (Note: the term "along a diagonal" means the bishop can cross a square it has already passed over, as long as it isn't travelling in the same or opposite direction when previously reaching that square)
