I'm not 100% clear on what you're asking, but if I can figure it out I'll do my best to help.
Are you asking how to get a dog to go from Front to Heel via left finish? i.e., something like this:
IMO the fastest/easiest way to do that without a ton of foundational work is via hand target or food luring like what's shown on that clip. Doing that big step with your foot is also helpful for many dogs because they can follow your movement to get into Heel, but for competition purposes you'd want to fade that out (a lot of trainers don't even teach it that way in the beginning to avoid needing to fade it out later).
For holding an object, I usually clicker shape for the initial hold and then for duration. That one can take a long time if you have a dog who doesn't like holding things (like, oh, both of mine...) but with patience and practice it'll come together.
