Google Analytics: Ignoring URL segments - can it be done?

I have a slightly unique issue whereby my web application has some URLs which look like this:

http://www.mysite.com/ext/b6bafaa21e9e8894458ee25038/members/home

http://www.mysite.com/ext/jd1323rij19f3f058ee25038/members/cool-page

http://www.mysite.com/ext/d428t9jmefb032b458ee25038/something/else

The first 2 segments of the URL is /ext/SOME_UNIQUE_KEY/ which is needed for this particular site.

I want my Google Analytics account to ignore the first 2 se开发者_如何学Pythongments and just track everything after this point IF the first segment is ext.

Is this kind of customization possible?

How would I achieve this?

Yes. You can use a regular expression filter:
