bidirectional mapping of inputs and outputs between original WDL and dx

[notestaff]

For the purpose of comparing the same workflow run locally on Cromwell, vs remotely on dx, one needs to know the correspondence of input and output names . I know dxWDL has the -inputs option. But (1) it cannot be run without creating new files on dx; (2) it does not intermediate or final outputs. Would it be possible to add an option to output a file giving the full correspondence?
