Mmm... the code is rather convoluted - trying to simplify it - but I'll try to put something simple together that uses parts of the original code and reproduces the...

I've have not forgotten about this. I've tracked where and how the timeslice MultiIndex is created and created another example that closely matches that (see below), but that one also...
