This mod will allow you to automatically roll greed, need, pass, or if the setting is disabled, let you manually roll on loot based on customized loot rules.

By adding customized rules, you can do things like roll greed on all Bind on Equip items, except in Karazhan. You could also let it ignore all Bind on Pickup items, to let you manually roll on them.(...)
I just noticed this addon and wanted to share.

I haven't had chance to try it out, but it looks pretty neat. You can read the full description via the link.
