merging drawig scale with same proportion but different definition??

[harinezumi]

is there a way to merge multiple scale that have the same proportion but different definition?

eg:

I work in meters and i set scale m1:100 as 1000 paper units=100 drawing units, in a previuos drawing I set m1:100 as 10 paper units = 1 drawing unit. Copying from file to file I end up having m1:100 and 1:100_1 and I have to find all the instances of the latter and change it before I can purge it. Of course they are both 10:1 so it should be easy for a lisp to find them and merge, eventually letting me choose wich definition I prefer.

I'd save it to DXF, open in an ASCII editor, and replace every instance of 1:100_1 with 1:100.  Save and open the DXF with AutoCAD, run AUDIT and pick Yes to fix any errors detected.

will this work even if 1:100 already exist? Can I put it twice in the dxf?

Long work around, anyway.
Thank you
