[CentOS] Switching screen resolution on the fly

Is there any way other than CTL ALT + and CTL ALT -
to set and or change the resolution of the X server when I want to.

Is there a way to so take me to "1920x1080" mode and then later
take me to "1366x768" mode.

With xvidtune I see the -next and -prev options but I was hoping for
jumping to specific modes. I so realize I can also edit out unwanted modes
in the xorg.conf but I'd rather not manually change items on a machine.

Thanks,

Jerry
