Sats don't move, and are in one big stack, so only the targetting priorities are of any use for them.

You can set strategies for fleets using the Chess Pawn icon on the right hand side of the lower row of order icons.

When editing strategies there should be an arrow box to click just below the list of targetting priorities...
Click that and a window will pop up with a list of options... you click four times to choose the four priorities.
