Check out the SMT tips available that are forked or split to hit both ends of the 0603. My Metcal has them and I am sure other soldering irons do also.
I no longer do 0603s, lucky if I can do 1206........

Any reason why small leaded caps cannot be just be bridged across the SMTs?
Lots easier to hold the lead with a tweezer and dap a little solder on
the end.

This is done by flowing solder onto all 3 pins on one side at a time (carefully!), then wicking the excess solder off with solder wick or a vacuum tool. Not for the faint of heart.
