This! For me it was one of those lightbulb moment to discover how morphing via a switch can be also really useful to achieve much more even and precise transitions than operating a morph pedal with a foot. For example short pitch dives a la "Lonely Boy" or a note sustain bloom fx (=precise gain+delay+eq buildup and decay) just by pressing a momentary switch.
To be honest, for me I wouldn't use morph for this. Having gigged Lonely Boy as your example myself, I find normal pedal pitch more appropriate...Same as Killing in the name or any dive bomb, I prefer to control the "Slurs" in, however appreciate other may prefer a switch....
