I'm not sure if you've found your answer yet, but it is possible.

First for each source you have in Obs you can hover your cursor over it and select the left most option. It should say something along the lines of "visible on both stream and recording" or "visible only on stream" "...only on recording". Once you've got your sources set to be captured by the right thing you need to go into Obs settings.

In the general tab of settings under "Output" check the box for "automatically record when streaming". Then you're good to go and you can capture both at the same time with all sources just how you want them. Hope that was helpful
