[Suggestion]Giveaways of DLC for games I own

I would like there to be some way for me to see all the giveaways of DLC for games I own on Steam*. Currently there is no good way to check for such giveaways, just methods that require a lot of work and are prone to human error. Steamgifts can already identify and hide all the DLC giveaways for games I don't own, so identifying and showing DLC giveaways for games I do own doesn't seem difficult.

The only problem I can foresee is that Steamgifts can't seem to tell if I own specific pieces of DLC or not. I'm guessing that Steam does not provide that information, which means I'll have to hide any giveaways for DLC I already own. Annoying, but acceptable to me.

*Excluding those hidden because I've told Steamgifts to hide them for whatever reason.
