Add option/tool for fix to output all paths that are being used with the fix?

[TobiasNx]

This might be to much to ask, but it would be nice to add a feature or a tool to output all paths that are being used in a fix.

e.g.:

copy_field("a.b","c") paste("test","d.e","g")

out put would be:

a.b d.e g
