Auto CLI from BofA?

Been reading the forums for quite awhile but this is my first post.

I had a secured cc from BofA that unsecured in April 2009 with a total CL of $1500.  I want to ask them for a CLI but am nervous about AA (I have a few late student loan payments from four years ago on my report) so was wondering if BofA ever does an auto CLI?  I was given a  $500 CLI when my card graduated and PIF each month (or have a max of $100 report).  I nearly max out the CL each month running things through to show usage but always make sure to pay it off before it reports.

My scores are currently 661 and 664.  In addition I have the BB RZMC and my student loans – no mortgage or car loan.

Any suggestions?

Thanks!
