Order h5 file hierarchy

Hello,

I'm trying to create a h5 file to exchange data.

I already create the structure but when I type "h5disp('xxx.h5')" the result is not ordered as the way I was expecting.

It seams that matlab order the fields alphabetically, however I want to order them in a different way.

So, my question is: is it possible to order/sort fields inside a h5 file by the order they are introduced when writting the file?

Thank you in advance for your help,
