File Paths for Files and Images for Many Sites on a Platform

Hello,

We have many sites on a platform, and the URLs paths to the images and static files on these sites begin with this format:

http://site1.domain.com/sites/site1.com/files/

So images and static files URLs end up looking like:

http://site1.domain.com/sites/site1.domain.com/files/images/logo.png http://site1.domain.com/sites/site1.domain.com/files/downloads/aboutus.pdf

Is there a way to make this something like:

http://site1.domain.com/files/

-- i.e., remove "sites/site1.domain.com", without bypassing core Aegir functionality? In theory we could try some Apache configs (aliases, rewrites, etc), but I would rather avoid that complication.

Thanks!

KM
