Pentaho 5.0 and adding Style in Settings

Hello,
does anyone resolved the problem how to add style in Pentaho 5.0? In Pentaho 4.5 it worked for me in this steps:

1. create css, html, js-files, save in different folders of pentaho-solutions folder(as used in example from webdetails) and
2. in settings for dashboard choose my style
How to get it working in 5.0 - the problem is that files are only uploaded directly after logging to Pentaho. The path can not work ...

I appreciate your help! Many thanks!
