Set of 5 Temple Blocks

I'm curious as to why the Temple Blocks only come in two different pitches? Typically, a set of five blocks is the most common you see, both in orchestral settings, and marching settings.

I've looked into this, and it sees to have had several requests sicne at least 2015, if not longer. It seems like a really simple addition to add in, and it's confusing as to why we are limited to just two pitches, when it is pretty common practice to have a set of five.

I don't think this is a super niche request, so I'm hoping this will get resolved soon. It's....interesting that this hasn't been addressed yet
