No, there is not.

That is an inherent problem of filenames.  Either you use relative
filenames, in which case they won't be valid if you access them from a
different directory, or you use absolute pathnames, in which case they
won't be valid if you move the files.  It's your choice; Kaldi lets
you use whichever one you want.  However, it should be simple to write
an awk script to modify the .scp files to change the directory.
