How do I keep the hash (#) in a URL while using utm query strings in Google Analytics?

Question

I've got a website that uses hash # to identify URLs. So URLs might look like:

www.mywebsite.com/somepage.aspx#productname

Obviously, "product name" is important here, and I need it to show up in Google Analytics, and by default, it does - the above URL shows up in GA as: somepage.aspx#productname

However, the tricky bit comes when I also need to add Google Analytics campaign parameters. They of course need to be added before the hash, so the above URL might need to look like this:

www.mywebsite.com/somepage.aspx?utm_source=source&utm_medium=medium#productname

However, if I do this, the page will just show up in Google Analytics as "somepage.aspx". Is there a way to make it so that even when using campaign parameters, I can still keep the part of the URL after the hash in the Google Analytics page name?

Solution

Why not use # as campaign parameter instead?

See this from Google Analythics:

_setAllowAnchor(bool)
This method sets the # sign as the query string delimiter in campaign tracking. This option is set to false by default.

Conventional campaign tracking URLs use the question mark (?) to indicate the beginning of key/value pairs that make up the query. If you set this option to true, your campaign tracking URLs can use a pound (#) sign instead of the question mark (?) to indicate the beginning of the query string.

Have you tried doing it like this: www.mywebsite.com/somepage.aspx#productname?utm_source=sourc‌​e&utm_medium=medium

Query strings won't work if they're after the hash. But, MrSponge's answer below seems to do the trick.

If I enable _setAllowAnchor, will "legacy" URLs which still use the question mark for Google Analytics campaign parameters still work as normal?
