'Select Matching Layers' across instances in a Slot

The slot feature has been incredibly helpful for enabling components to have modifiable contents and I’m absolutely loving it.  I do consistently find myself running into a thing that I wish was easier/facilitated by the UI.

If I have several instances of the same component in a slot, such as rows in a table or cards in a gallery layout, etc., it would be incredibly helpful to have access to a feature similar to the “Select Matching Layers” functionality that’s available for general selection, but to have it apply across the instances in a given slot.  That way if I want to select all of the items in the first ‘column’ of a table row and modify them, or select all of the body text fields on my gallery cards, I could do that with a single button instead of having to manually select each one. This would also be incredibly beneficial when some of those instances appear ‘off screen’ because the area is set to scroll.
