Bulk Linking contacts to accounts

[ontiversmo]

I have imported 1500+ contacts into BCM. I have attached (in bulk)
categories to each contact (so, I have 4 or 5 categories spread accross 1500+
contacts).

Now, I want to apply each of the contacts to accounts. There are only approx.
8-10 accounts. I don't want to open each and every single contact to
associate an account. Is there a way to select a subset of my total contacts,
and associate a single account to those selected records?

Thanks!
