[Feature] Making common fields as owned item and favorite/desired item

[lopiv2]

I would make common fields for every collections two checkboxes for owned item, and favorite or desired item, so we would be able to count owned items, missing items, and so on. So that way We dont have to add the checkboxes by our own. This should be collection common fields like names, quantity or images

It would be a nice addition, so i think if the app is a collection manager, what a best way to track collections like this.
