Sure there is.  Easiest solution: put your slots in the milling layer  
as "correct", and write a ULP that processes the routing layer and  
outputs the excellon format as above in a separate file that can be  
appended to the main drill file.  (or, perhaps it can append to the  
drill file automatically.  I don't recall whether EAGLE ULPs can  
append to existing files...)

(alas, last time I looked, you couldn't invoke the CAM processor from  
ULPs, or I'd suggest using a ULP to do ALL the cad file generation.)
