[AA] Add Tall Height Connecting Pieces for Modular Playground Pieces

I finally got the chance to build a playground and while building it, I noticed the playground equipment only has short height connecting pieces for several items, leaving us with no way to connect the tall tower to another tall tower and no way to get onto the tower from the ground aside from climbing up the slide (which is a fun option, at least!)

 We have four options to get onto the short towers--climbing the slide, the ladder, the steps, and the climbing wall; and we have two connecting pieces for short to short towers--the bridge and the tunnel. I must have scrolled through this a million times trying to find a tall connecting tunnel/bridge in order to connect two tall towers only for it to be impossible. 

It would be nice to have more ways for kids to get onto the tall tower aside from the slide or going from short to tall tower, and it would be nice to be able to connect the two tall towers with tunnels/bridges.
