That would be a part of the "others" section. Just make sure you state it and ill get back to you on that. The body actors are somethings that I'm still thinking on. There are some mods that can act as a camera but I am unsure about them. Body actors will be the back up if those mods fail.

Generally speaking you can decide to take multiple positions. I will be limiting them to only two positions however. The more jobs you take the more work and effort you put in well you also divide attention and use up more energy. Anything more then two you are really pushing yourself and as this is a long term project you have to be in it for a long haul. You can not burn yourself out within a few days of working. So to answer that question, yes you can have two positions if you choose to and no more.
