Assetic Symfony2 less+compress filter - symfony

Question

Is there a way to make assetic automatically compile and compress .less files?
I tried this config:
assetic:
debug: "%kernel.debug%"
use_controller: true
bundles: ['BloggerBlogBundle', "FOSCommentBundle"]
#java: /usr/bin/java
filters:
cssrewrite: ~
less:
node: /home/igor/nvm/v0.8.16/bin/node
node_paths: [/home/igor/nvm/bin/node_modules]
apply_to: "\.less$"
yui_css:
jar: %kernel.root_dir%/Resources/java/yuicompressor-2.4.7.jar
apply_to: "\.css$|\.less"
But this results in .css files getting compressed and .less files getting compiled. I can't make it do both: compile and then compress my .less files.

Here is my config and twig code for compiling + compressing .less files in the same time:
config.yml
# Assetic Configuration
assetic:
debug: %kernel.debug%
use_controller: false
java: %java_path%
filters:
less:
node: %node_base_path%
node_paths: [%node_lib_path%, %node_modules_path%]
cssrewrite: ~
yui_css:
jar: %kernel.root_dir%%jar_file%
yui_js:
jar: %kernel.root_dir%%jar_file%
In my twig:
{% block stylesheets %}
{% stylesheets
'#MyBundle/Resources/public/css/event.less'
'css/colorpicker.css'
filter='less,?yui_css'
output='build/event_layout_2cols.css'
%}
<link href="{{ asset_url }}" rel="stylesheet" media="screen" />
{% endstylesheets %}
{% endblock %}
And here is the command to both compile AND compress:
./app/console assetic:dump --env=prod --no-debug
Hope that help!
