De-sync nested components properties

So, i have a component - List, which contains list items as nested components. There are two types of list items, which are different components (not a variants of the same, though they both have their own variants and properties). I created an Instance property in List component and linked every list item to that single picker, so i could pick one of the two types of list items. The problem i have is that all list items sync their properties, so i cannot have list items that differ from each other. The only option i see is to link every list item to its own Instance picker, but it will overcomplicate the properties, can i somehow de-sync the properties of items, that are linked to the same Instance picker? I hope my question is understandable
