Choose Not Reset Filter

[HaoboZ]

Is it possible to add an option to when scanning artifacts to not reset the filter? Mostly just a speed thing, for example I'm only strongboxing 1 artifact type but it needs to scan through the whole list to get an updated list which is pretty slow if you have a lot of artifacts. Instead if it doesn't reset the filter, I can have it just scan 1 artifact set and update that to the site I use. Just an option so the default behavior doesn't change.
