Attaching timings to palettes

Been attempting to attach timings such as delays to my palettes, mostly for use in live playback. Is there an easy way to put timings into palettes so when the palette is executed, the timings will affect it? Fanned movements and color wipes are the kind of things I would like to put into palettes...

or...

can I apply fade times on the fly to pre-existing palettes? such as some functions on lesser consoles...
