Dynamic Text for URLs (NOT simple QS APPEND!)

I need to be able to parse querstring paramters into a URL

Take this URL for example
QS-Example.com?subid1=test&subid2=test2

On that page is a link (button, image, whatever)
https://some-other-url.something/

I need to be able to do (2) things
https://some-other-url.something/subid1/subid2
would parse to
https://some-other-url.something/test/test2

and/or
https://some-other-url.something?newparameter=subid1&newparameter=sub2
would parse to
https://some-other-url.something?newparameter=test&newparameter2=test2

Please, before anybody suggests - I am not looking to append query-string data to the url on button or link click - the parameters from the source page need to be remapped into the URL tail in some cases and in other remapped to new outbound parameters in the link.

In instapage the [DTR] parameters can be used
so
https://some-other-url.something?newparameter=[subid1]&newparameter2=[sub2]
or
https://some-other-url.something/[subid1]/[sub2]

We work with multiple downstream affiliates and I need to be able to pass collected parameters into my links to track in their systems.

Anybody?
