Passing assetid variable through Paint Layout

On asset with id 14323 is applied Paint Layout1 that (beside other contents) nests Asset Listing to list direct children of asset displayed by Paint Layout2.


Can I, in any way, pass asset id (14323) as a variable to Paint Layout2?



For now in Paint Layout2 I nest Asset Listing that lists direct parents to find assetid, but I don't like this solution.
