LSMW accept file from logical path?

Question

Dear All,
Can LSMW designs for conversions accept file from logical path?
The requirement is during actual conversion execution -the conversion team can store files anywhere they want, configure logical file names/paths and use our LSMWs without needing program modifications.
Kindly let me know.
Thanks in Advance
