ent_decal: stack order of decals

When I apply a series of decals onto the surface of an object using the ent_decal function these decals appear in a strange stack order: the first created decal [1] appears in the front while the last created decal resides in the back [2] and therefore is (at least partially) hidden. Is there a possibility to reverse the stack order? In my application I would need the last decal to reside in the front.
