Is there a way to deal bleed damage as a psyker without going melee?

As the title says.

I'm making a psyker executioner, and I'm planning to focus mainly on ranged blasts with pyromancy (powers and staff) and santic (staff). I can apply toxin with biophysical distortion, burn with pyromancy (obviously), but I can't figure out a way to apply bleed damage as a psyker without doing melee.

I know that pyro-blade-ex is super ultra strong, but i want to maximize my exploding DOTs as a ranged blaster.
