Preview processed HTML file from another (dist) directory.

[oliwerAR]

In my settup I have some html files in app/ directory, which are proccesed (by gulp) and outputted in dist/ directory.
The gulp settup includes browser-sync preview running on http://localhost:3000 but it forces me to manually navigate to the speciffic html file.

What I want to achive is when I lunch a preview on html file somewhere in app/ the preview displays corresponding file from from dist/ (or from the browser-sync on http://localhost:3000).

I tried tinkering with root and proxy setting with no luck.

Please, help!
