Whos Online PHP

[Bilderback]

Recently, I have added a couple Products which did not include the WOL plugins and showed as Unknown Location: when a user was viewing.
I had always countered this by adding my own plugins to each product utilizing the location_process and location_unknown to fix.
Now I have run into a situation where a product uses multiple files (5 of them)
Instead of adding 5 plugins for each unknown location, is there any way to combine all the files as a single unknown location plugin?
How would I do this?

PHP Code:

if ($filename == 'file.php')
{
        $userinfo['activity'] = 'file';
} 


Would I simply put an array(file.php,file1.php,file2.php,file3.php,file4 .php) ?
