Some mounts have a setting to do this, but many (most?) do not. And I'd guess this ends up be a per-driver thing, though in principle it doesn't have to be. As a former ACP user, I know they can do it for mounts that have no built-in support for consistent approach slewing. 

So the question is, is this already hiding someplace in INDI/Ekos, or would it be a new feature that has to be added?

One thing that has lead to me to wanting this is that I'm trying to figure out a way to do dithering via pointing for when backlash is an issue; and yes, I've got too much backlash to do dithering well via guiding, especially in Dec. And my Canon T6i cameras show some horizontal banding that I suppose I could work around by rotating the cameras, but I kind of like the camera axes to line up with RA and Dec....

If I treat the problem as it I were building a mosaic that overlaps about 95% and had consistent approach slewing with some sloppy tolerances, I think I can end up with an effective workaround. But consistent approach slewing would be good in general since it would mean there should be little backlash to deal with at the end of pointing.

If I understand the "consistent approach" term, you would like a slew to point to a target at an offset from the real target, so that the mount backlash may be cleared with the final adjustment.

I think that you can achieve that half-automatically by asking an alignment to a preliminary target on the "proper" side or the final target. A subsequent alignment to the final target will only move - slowly - in the direction clearing the backlash. Of course, this preliminary target depends on the type of mount and its current orientation.

But that could be an interesting feature to develop indeed.

Now, when you mention mosaics, the latest change in the tool allows you to make minimal adjustments when slewing from one panel to the other. Ascension changes will be done on reverse sidereal direction, but, yeah, declination will go both ways. I agree consistently removing the backlash here is only theoretical thought, as in practice adjustments might happen in both directions.
