Selection of objects of the same layers

[TextTL]

I'm using SelectionLayer to select group of objects, and having issues with objects of the same layer-id but overlapped. I looked at the codes and found that SelectionLayer uses pickObjects, which supports 1 depth per layer. I looked at deckgl, and found pickObject allows more depths > 1, but does not support selection of a boundary, Is there any way to allow both boundary + depth?
