Ability to specify custom payload position(s)

[ph5i]

Currently, the payload position defaults to the end of the URL. Being able to specify a custom payload position would be beneficial in certain cases.

For example: ./nomore -u example.com/organization/100/user/200?foo=bar

In this case, one may want to target the "organization ID" (100) and/or the "user ID" (200) instead of inserting payloads at the end.

An added bonus would be if it was possible to specify multiple positions.
