Able to see DLC for a game in my steam library when buying in the Paradox store?

So I bought a bunch of Cities Skylines DLC today in the Paradox store sale. I originally bought CS on Steam and have also bought DLC there.
Even though I checked, I accidentally bought a couple of items I already owned (as I found out when I applied the Steam keys).
I've opened a ticket to refund the 2 DLC I already had, but as a better solution, is it possible to show DLC already owned in a linked Steam library, when browsing the Paradox store?

It's actually something that we're planing for the updated accounts website that we hope to release next year so yes, it's coming !
