Sources for poison damage converted to Bleed damage

Are there any sources for Poison damage to be converted to Bleed damage? I’m working on a bleed pop Marksman and Acidfletch with Sanguine horde combined with Sanguine Obsession in the Puncture skill tree makes Hail of arrows a bleed proc monster. Only dead weight on Acidfletch is the Poison damage. It’s probably still good without the conversion but it’d be sick if it could be bleed damage.
