Default Organising documents in Pocket Word

It seems like it is impossible to organise the Word documents in subfolders like in desktop Word:

What I would like to do is to organise all Word documents in a folder called Word, in which there should be subfolders, which should contain the Word documents.

When I open the document list with the Word folder I only see a list of documents actually in the Word folder, I can not see any subfolder at all and not the documents in the subfolders.

Is there a way to work around this, or should I use another software to replace Word?

Best regards
