Possible to show the RMS number on the meter?

[A Tolerable Quietude]

I'd like to be able to see the RMS as well as the peak in the console.  I know that I can set the meters themselves to show both, as outlined here.  But that still shows only the peak as a displayed number below the meter.  Is it possible to display the RMS as a number as well, or instead of the peak?

There’s many free meters available which you can add to the effects bin. The Cakewalk meter is strictly peak just like all mixing consoles have.  Span has RMS and LUFS as example.

Thanks, I can use a plugin.  Span looks useful!  I just wanted to be sure I wasn't missing a setting somewhere.
