Technically, they should let you do that, but I'm sure there's some
operational reason why it's easier on ATC to have two distinct flight

plans, so I'm willing to go with the flow on this. The pilot and ATC

need to act as a team for things to work efficiently. If one team
member says, "please just do it my way" and it's no big deal to
comply,
there's no reason to get bent out of shape over it.

I think the briefer said that Detroit Approach requested or required
them to make a distinct plan for flights crossing their border, even if
you're not landing. If I'd go PTK-FNT-PTK, Flint would give me a new
clearance and new squawk code when I was done with the practice
approaches.

So, maybe that wouldn't apply to 3BS-LAN, but it would to 3BS-PTK. Hmm.
