Importing Layout Sketch Dimensions

Many times when modeling a part, I use initial layout sketches and/or reference sketches throughout the feature tree, that I use to reference my features to.  These are un-absorbed sketches.  However, they contain a lot of crucial dimensions used to create the model in the end.

How can you import dimensions into a drawing, from these un-absorbed sketches?

Thank you,

Seth
