Placeable bundles in pocket edition

So the problems with bundles is that in a touch pad device it's impossible to use a bundle in your inventory right? Well here's a solution. I didn't make it up myself. I heard it from someone, but I can't remember. But since we need a solution for bundles, here is one. In Minecraft Bedrock Edition (not Java Edition), you have 2 ways to use bundles: the old fashion way you can use them on Java Edition, or in case you're using a touch pad device, you can place it down. The inventory should have one empty slot. You can place anything in that slot. If it doesn't fill the bundle, another empty slot will appear. And there will always be another empty slot until the bundle is full.
