For `cp some/long/path/to/foo.txt some/long/path/to/foo2.txt` I always liked brace expansion, for example

`cp some/long/path/to/{foo,foo2}.txt`

(Though foo{,2}.txt is even shorter)

This sounds like something the Stylish browser addon could do for you easily.

It could be an additional multiple choice field, with N+1 options. Both would need to be filled in for the form to be valid.

This is easily prevented by additionally marking the number of candidates chosen.
