Why would it be "uselessly time-consuming"? Let's go over the ideas I had in my poorly-spoilered post ahead of yours, one by one, explaining why they are neither useless nor too time-consuming:
1. Having dwarves stand still.
This could be useful for a wide variety of things, from having militiadwarves not charge into combat without their comrades to getting a dwarf to not leave his safe, secure bunker. This would be simple; just disable all job-grabbing or meandering until the dwarf gets hungry or thirsty enough to need to stop.
2. Having dwarves go somewhere specific.
From a more accurate station order, to having the dwarf get to a safe, secure bunker rather than running willy-nilly about the surface, to to exploring the caverns with people that won't suicide-charge every troll or GCS they see, a "Go here!" order would have many uses. You could use the code for stationing military dwarves, or simply the normal pathfinding code.
3. Having dwarves do specific tasks.
This would allow you to A. choose to have the noob cook cook basic meals easily (and other situations where you want one, specific dwarf to do a task) and B. fiddle with the natural order dwarves to tasks in (e.g. getting engravers to engrave memorial slabs and not smooth your halls, or master masons to make statues, not walls). Yes, most of this can already be done by fiddling with burrows, labors, and such, but a more straightforward way to do this would be nice. Dwarves already pick jobs to do on their own; this would merely require that the player be able to take the "choose" step out of the next job the dwarf does.
4. Choosing materials for tasks
I know you can do this with stockpiles, but, again, a simpler, more...one-use way to do it would be nice, especially if you wanted to (for instance) make a statue out of an economic stone (i.e. hematite, for your militia commander) without risking having all of that stone being turned into blocks and mugs (i.e. depriving you of iron). It might be a bit harder, but as dwarves already choose materials for jobs, it seems like the interface would be the toughest thing. And an interface like that needs to be done, when adventurers can do reactions.
