Please add a command block feature that only exists in bedrock

Hello Minecraft, 

If you know that in Minecraft: Bedrock Edition, there is this command block feature that lets you add a delay to command blocks like when you want to have a repeating command block activate once every second. I mean that little box that says "Delay in ticks". I would love it to be in Minecraft: Java edition too so that I can make a bedwars item generator without having to go through the troubles of making a super large and ineffective repeater clock. I would LOVE it if you would add that in as soon as possible so that I can make my vanilla bedwars.
