Is the Count Event available in CCS version 5.5.0.00077?

We are using Tiva C Series TM4C129x Tiva C Series TM4C129x with CCS 5.5.0.00077, we need to count the cycles between two breakpoints, however the Count Event seems not to be avialable for us, we don't see it as an option when adding breakpints.

Is this because of the CCS version?.

Thanks.
