Missing Cycle timeout speed setting

Maybe I missed it somewhere, but there is no timeout setting for the Jquery Cycle rotation, i.e milliseconds between slide transitions which is set to 4000 in the jquery.cycle by defaut. This is pretty fast rotation for ads, so would seem sensible to have a setting in the View alongside the less useful transition speed.
I've just changed the default in jquery.cycle after not finding a setting anywhere in the admin ui or the View, or in the module files.
