Is it possible Notepad++ to change the theme based on current filetype

For example, if I open a text file, notepad++ would open it in 'default' theme. But if I open a php file for instance, it would open it in 'custom_theme1'. I know notepad++ is highly extensible, so I wasn't sure if anybody had ever run across a plugin that could do it. Or could a plugin even be written to do this?

Unfortunately, at this time it appears that this functionality is not a part of Notepad++. However, it has been submitted to the developers as a feature request.

Let Language style change theme, or global bg colour

I would like for a language definition to be allowed to change the global theme for when that language is loaded, and/or at the very least change the global background colour.
