Thanks a lot for getting back to me!

Well the card *is* actually in your inventory, and you are using it in the deck, right? Even if temporarily it's in a different deck. I would just mark it as "From Inventory", since that's how it is...
To clarify: the card *is* in inventory, but it's *not* in the deck, even temporary. I use actual proxies to not move the card back and forth all the time, so to me it does make sense to mark the deck entry in a special way.
Marking with a #proxy also didn't work for me as I want to see the deck value being realistic.
Is the problem actually that when you look at the inventory you want to know in *which specific* deck a card currently is, as opposed to which deck you could move it to?
Yes!
Let's say I have 1 copy of Heroic Intervetion.
When I open the Heroic Intervention page, I want to see where is the original.
The same applies to cards I have multiple copies of. E.g. i have 10 decks and only 7 real sol rings cards. I would like to know where the real ones are in.

This is confusing a bit, indeed. Selecting "Default Printing" means actually "not assigned to anything". So when you switch the deck to built, it will try to find things in your inventory that match.
You can obtain the effect you want - but you need an extra click for it: instead of "Default" select "Custom printing" in that dropdown, then click save in the panel (without actually selecting any kind of details on this custom printing). This will force the matcher to not guess anything for it when you change it to built.
This does the trick for me, thank you for the solution!
