Group blocks files in subfolders

[johntheideaofnow]

Hi, Thank you for this plugin, it makes it very easy to create blocks in Timber.

One question, is there a possibility to organize the -preview and -example files in separate folders inside the blocks folder (I have about 20 blocks and each one has -preview and -example, in total there are 60 files ... and if the number of blocks increases it tends to become uncomfortable to manage so many files).
