Prefix Title on forumdisplay

[WiBu]

I'm looking for a way to display the prefix as a title when viewing threads with a certain prefix in forum display.

For example, if a user selects to view threads prefixed by "Modifications" a title would display at the top saying something along the lines of "Viewing threads marked Modifications".

If a user has not chosen a prefix it will display something like "Viewing all threads".

I don't need help with the front end code, I'd just like some help on finding the variable to use or getting pointed to a guide on how to pull the variables needed using a plugin (I've searched and searched but come up with nothing).

Thanks in advance.

Edit #1:
After a little thought I figured this might be able to be done by using <if>. I still have no idea if it's possible to do something like...

<if condition="prefixid=['1']">Viewing XXXXX</if>

<if conditon="$vbulletin->GPC['prefixid'] == 'blabla'">
    Viewing XXXXX
</if>

blabla - is the the prefix id you assigned to the prefix when you created it.

Completing rising this thing from the dead, but it's the same question, just needs a little refinement to the answer.

I'm wondering if there's a way to display the prefixrich on the forumdisplay when viewing all threads from that prefix. Haven't come up with anything from big search (found my old thread while looking).
