Q: Keynote. Typewriter build. Timing.

OSX 10.11.4 ;   Keynote 6.6.2 (2571)

I want text on a slide to appear (build) via "typewriter" effect.

I want to time the build of each paragraph independently due to the varying lengths of the paragraphs. (Since one is setting the build time by paragraph and not by individual letter, long paragraphs need more time to build than short paragraphs if one wants each letter of each paragraph to appear at the same rate.)

I used to be able to time the build for each paragraph in a text box ndividually. For some reason unknown to me, now I can no longer do that.

Does anyone know how to time builds by individual paragraph in this latest Keynote version??

(Note: I can set the build to "build by paragraph", but that sets the same timing for every paragraph in the text box. That is not what I want. I want to set the individual build times for the individual paragraphs.)

(Additional note to Apple... In builds like "typewriter" why not have an option to set build time by individual letter so that users could easily have letters appear at the same rate??... you know, kinda like how letters appear when a person is actually typing something.)
