So I figured I'd make a note here so I don't forget again and for anyone else in the same boat. It's just <<- instead of <<. For example if you want to keep indentation within a loop:

BASH:
  1. for i in 1 2 3 4;do
  2.     cat<<-EOF
  3.         This is loop $i
  4.         More advanced stuff could go here
  5.     EOF
  6. done

You can use whatever you want to indicate the end of the input instead of EOF if it floats your boat (as long as you use the same thing both times) but unfortunately <<- doesn't work with spaces for indentation (although I'm a tab man myself).
