Selecting a specific property value

[SuperCowProducts]

I want to do something like this:

https://hub.toolforge.org/Q47455628?property=P953&P2701=Q42332

At the moment it doesn't recognise the P2701=Q42332 part (which I want to use to select the value linking to the PDF document) and is just redirecting to the recognised bit, in other words the more general query https://hub.toolforge.org/Q47455628?property=P953, which by default chooses the first available value.

Any ideas out of this?

[UPDATE]

It looks like the critical point is that it doesn't support qualifiers. Perhaps I could add a qualifier= option to the code, that depends on property= ?

Maybe something like qualifier=P2701:Q42332?
