"Update metadata" messing things up when a game is not on DB; can I force a strict scrape?

[B-B-Lee]

Hi, I'm having problems with the "update metadata" feature on a very BIG C64 collection.

I imported anything from the GameBase archive without downloading anything from LB DB not to mess up with names and versions and I've done A LOT of manual and scripted work to combine regional versions, duplicates, hacked versions and so on... I divided my whole collection into two platforms to keep public domain and unreleased games away from the main platform and I would like to use the "Update Metadata and Media" feature on the main platform to download media.

The problem is that LaunchBox try to guess too much.... for example I've a game that is called "anagram", that simply does not exist on LB DB, but when updating metadata (no replacement selected) LB decide that the best match is with a game called "xanagram" and associate and download media from it to "anagram"... this happens for hundreds of games, making the scraping process useless, or even damaging (I can not double check 35000 games)... is there a way to FORCE a more STRICT scraping?

I know that C64 is a mess of a platform, but it's my first gaming platform, so I would like to achieve the best results as possible.

Thank you very much!
