Add Base Slug To URL

I just tried the current version and there’s no option for a base slug like “go” or “out”.
Example: https://prettylinkpro.com/out/plp

Am I missing the option somewhere?
If not, is it coming soon? Date?

I don’t want to implement this solution and upgrade to the Pro – only to have all of my links need to be changed and cached search links become invalid.

There may be an answer to this, but there’s no easy way to search for responses on only this plugin.
