Currently short.io seems to always generate the trailing slash / (when using $1/ in the Original URL) or always remove the trailing slash / (when using $1 in the original URL) even if there had been a trailing slash in the request path. Simply preserving the request path and appending it exactly as it is (either with or without a trailing slash) does not seem possible with short.io.

This feature request should allow preserving the * part for a 404 or wildcard slug (including the optional trailing slash)

We would like use the to original URL https://target.org/path/$1 while preserving the trailing slash (only if it exists). So for example https://source.org/foo should redirect to https://target.org/path/foo and https://source.org/foo/ should redirect to https://target.org/path/foo/

The original request path component should be preserved in $1 (including an optional trailing slash) and placed where $1 is located in the original URL.
