As far as I know, there isn't an easy way to do this.  But it never hurts to ask, right?

Past encoding practices at my institution inserted a false c0 layer in EAD finding aids.  For example, 

My understanding correct EAD encoding:
OR

Past practices at my institution:
OR

Other than hand-coding, is there a way to promote the c4s to c3s and eliminate the false level?  I haven't used Archivist Toolkit or many other collection management software packages that might have this functionality.

Thanks!
