Is there a way to crawl only a specific lists within one site collection?

We have: - one specific List that needs to be indexed every 10 minutes http://site/lists/Invoices - several archived lists: http://site/lists/archved1, http://site/lists/archved2, etc that need to be crawled only once a week.

I want to have one search scope for each of these cases with separate schedules. Unfortunately, I've found out that it's not that easy as I thought.

I don't think crawl rules is an option since they will apply for the whole website.

Any help will be greatly appreciated!
