How do turn off Sexlab gender preference?

[boobi3]

Let say there are FFFM (F = Female, M = Male). Animations for FFFM seem to show up on the list of current animations, but gang bang animations that are MMMF aren't showing up. Is there a way I can turn off gender preference and let FFFM plays the MMMF animation anyway, just that some female uses strapon to replace the male actors?
