Some do have a way to partly use a cartridge, stop and finish, some don't. However many fiund that even if the unit is supposed to work that way, it doesn't always work out.
There's also the issue of seating, and the possibility of having to bleed ressure, reseat and fill anew. I strongly suggest a hand pump of some kind as a back up, and you can use that for the seating inflation up to 10-20psi, then if all is OL to finish with CO@.
If time is critrical, (tri-athlete in a race) and/or you have confidence that your tires seat right every time, then a straight shot with CO2 is fine.
