Using a MACRO to change specific reference file logical names

I was wondering if it's possible to change reference file logical names using a MACRO for instance:

I have reference files in a master file named 12345drng.dgn, 12345reqd.dgn and I need to have something that will go to each files properties and change the logical name to DRNG and REQD so I can run through some batch processess I have.

I tried recording a MACRO of clicking references, doubleclicking then changing the logical name but it doesn't store when I change the logical name.

Is there something similar to "reference properties" i can use that uses a portion of the file name like "drng" instead?

Thanks!
