We use a workaround.  Simply rename your accounts with a leading exclamation point, then sort the list by name.  We wanted our bank accounts listed first, followed by our credit accounts, so we used 2 leading exclamation points for our bank accounts.  

Our list now looks similar to this:

!!Bank Account 1
!!Bank Account 2
!Credit Account 1
!Credit Account 2
!Credit Account 3
etc
etc

It isnt ideal but it works!
