Cushions should be able to move!!!

The new Cushion Block should be able to move together with slime/honey blocks to make easier transportation with flying machine so we dont need a composter for example!!!This would be a lot more simple and also it will look more cool!!!Also it will be more cool to be able to move with piston/stickypistons.A good example is an elevator you can use the new Cushions to move them around to make an elevator in a house!!!This would be revolutionary it would bring so many new ideas and bring life into your build but in an automatic way!!!
