Transforming a boule or batard into other shapes

Lately I've been making my favourite winter sourdough. Shorter days and cold weather always seems to call for heartier loaves so I laminate mine with tons of crunchy whole hemp, nori flakes and house made rice or oat koji. I shape these into a boule or batard, retard outside overnight and just before baking smear them with tons of good quality EVOO and kosher salt. Then I bastardize them by turning them into smaller shapes I can freeze. This is mainly so we don't devour an entire loaf in one setting. These breads are somewhat addictive ( if I do say so myself)!
