Check for specific entity above a block

Is there a way to check if a certain entity is above a block. Such as if entity (spider) is y+1 above a block, then place (spider egg) in slot 0 of block x,y,z if it has inventory. Or if entity (zombie) is y+1 above a block, then place (zombie egg) in slot 0 of block x,y,z if it has inventory.  Is there any way of doing this currently in Mcreator 2019.5 EAP (46321)
