layers

Hi

In a model I have some sketches, in the drawing I would like to puts some of these sketches on a separate layer. So Can I make a layer and go in the tree and pick those sketches to move to the new layer or something like that?

The reason I would like to do this is when they get save out as dxf for machining that the layer the model is on can be turned off and just see the sketch that were picked.

Thanks
