I don't know bread machines, can they even take SD with it's odd timings?

Well at the risk of blasphemy here, yes they can - if you get one with
a french bread (or similar) setting that is at least four hours
long.

I add about a cup and a half of batter consistency starter to about 2
cups of flour, plus 1T sugar, 1/2t salt, and about 1/4 cup of olive
oil. Using those proportions, I usually need to add an extra dribble
of water to the ball of dough as it starts it first fast mixing cycle
to get everything to stick together. Loaf rises great- often
threatening to push up the lid of the machine....

Not the way to go if you're looking for that signature sourdough
taste, but it's healthy and a good excuse to refresh your starter in
the middle of the week.
