Pocket edition bundle issue

So we all know that pocket edition struggles with bundles, I think I have a solution. What if when you double tap the bundle, a small pop up will show the contents inside of it. There will be an inventory slot with a plus in it, you can then drag an item onto the plus to add it into the bundle. I think this could also be a quality of life feature on other devices. There will be an X in the top right to exit this pop up. Another quality of life feature could be double clicking an item inside the bundle and any item of that sort will automatically be picked up by the bundle as long as the bundle is in your inventory.
