How to use Paths

[destrugter]

I'm trying to figure out how to use Paths. From an example I saw for the CLI you can do -P "home:final/path" -P "temp:ssd/path" -o "file-name.%(ext)s". When I try this with the Paths property, I can only set it once not multiple times which is leading to my confusion on how to use it, or if it was forgotten to include multiple values?
