Is there a way to get these guys to report the CL to the credit bureaus?

I have a few cards, most of them report the CL. I pay in full every month, yet my score constantly suffers from using too large a % of my available credit.

This card supposedly has no limit, which is bogus, as everyone knows. The only effect of this "no limit" policy is the negative factor on your credit report. Any way around that?
