Joining a branch drain line at a 30 degre angle?

In order to bring a sink drain line over to the main drain line, I really need to join it in at a 30 degree angle. 45 degrees puts the wye outside the building. Searching on google for a 30 degree wye produced no results, so I'm guessing this either doesn't exist? What do plumbers normally do in cases there they need a 30 degree wye in the waste line?

I could go 90 degree from the fixture, 45 degree bend, then 45 degree wye, but I'd rather keep the line as direct as possible without the extra direction change in there if possible.
