... what is the problem with the boards having a different com port from one another?
It just is wasteful.
Is there any way to cause the computer to assign the same comm port to all of the Arduino's I plug in?

Someone mentioned the unique serial numbers of each FTDI chip which causes different instances - it looks like I am stuck, as that doesn't appear to be anything I can affect.
If you read the FTDI's data sheet on its Internal EEPROM (section 4.2), you'll see you can (re-)program its serial number.http://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT232R.pdf

That is exactly what I was looking for.I programmed all 3 devices with the same serial number, and they all now show up as the same comm port!Ain't the internet wonderful...-- Steven
It is also possible to fix the serial number to a fixed 8-digit alphanumeric string; however we do not recommend this as systems will only recognize the first instance of such a device connected to a PC.
... you will give up the chance to be able to have more then one attached to your PC at any given time. So a trade-off of sorts?
