Gantry framework and template : alternative css file ? - Joomla! Forum - community, help and support

hi,

i'm working on joomla 2.5 site gantry framwork , gantry template 4.0.5.

for particular section of site, want change block colors , other rules not accessible via gantry options in administration.
--> can't this.

i don't want 2 templates, because particular pages need have same content @ same place (and in stupid maintain double template site evolves). want change painting, speak, it's clear in part of site.

--> there way, within unique template, tell gantry load alternate stylesheet when user visits particular section of site ?
i know can dupliquate template style, can't seem change else gantry framework options. there way assign css file gantry override ?

it works fine with, say, beez20 template :
- duplicate template style
- in advanced options of template style, pick css file want applied (provided you've created , added in templatedetails.xml file).

but gantry not seem offer kind of css menu, , options don't mention block colors, borders or things that.

i hope question clear enough. ideas ?
thanks
