How to exclude files from assetic, if i use * selector?

[lavrikanec]

{% stylesheets output = "style.css"
'../app/Resources/blocks/*/*.css'
'../app/Resources/blocks/*/*/*.css'
%}

My repo looks like that:
blocks
header
header.css
header_ie.css
header.html
footer
footer.css
footer_ie.css
footer.html

And there is a huge amount of blocks (about 50), so i dont want to manually attach each .css

The point is that i dont want to *_ie.css files to be included in the general styles, but i don't know how to write a condition

'../app/Resources/views/blocks/*/*[^i][^e].css' doesnt work,
'../app/Resources/views/blocks/*/*(?!ie).css' too

Frankly, im not even sure assetic supports regexps

Please help
