For SexLab animations, you can use the C key for up and Shift+C for down- that way the alignment change should be "remembered" by SL for that animation.   For all SoS-Full animations, PgUp / PgDn work also, but I do not believe that SL captures or retains those adjustments.   I use UUNP and SoS-Full, and my men do not have permanent erections. You should probably post that issue on the SoS page.
