multiple UVs in the same material

Hello,
i’m just trying to setup a material in Blender make of 2 textures, one have an UV mapping, the other another UV setting. Is this possible? Or there’s only one UV per material ? I’ve no problem on setting the other mapping modes (Glob, Orco, etc) but that one the UV editor seems to not have a “set UV for that texture” feature.

Thank you

currently there is only one set of uv coordinates allowed, this is planned to change but not in the next release [that I know of]
