Perch Gallery URL Slug

Perch Gallery URL Slug.

Is it possible to change what field generates the url slug?

I’m not using the gallery plugin in a traditional gallery way, so lets just say for this example there will be a lot of galleries called “Hats” so the slugs will be hats… hats-1.. and so on. and the urls (presuming at this point I’m not using clean url rewrites) /album.php?s=hats-1 etc..

Would it be possible to get the urls to be: /album.php?s=albumTitle_hatColour

hatColour is already a required field in album.html, just not sure where, what and how complex it is to change the url so the galleries are more SEO friendly.

Thanks Steve
