Using /fill in Bedrock Edition

I first discovered this when trying to build a house out of dark oak planks. It was a large build, so I was using /fill. I typed in my commands and typed in “dark oak”. I noticed that the list of dark oak blocks did not include the planks. When I tried typing “planks” It had “planks” (oak planks), cherry planks, bamboo planks, mangrove planks, crimson planks, and warped planks. I did not include any older planks like spruce, birch, and dark oak. Before you say “you just have to put in the wood number” I am aware of that. The reason I am making this is because I think it is inconvenient. I is not Ike this on Java. Mojang fixed that years ago. Why not fix bedrock?
