MSP Flasher - length of Intel hex lines when reading

I'm using the command line MSP430 flasher, v 1.3.3 I believe, in XP, and when I read the current contents of a device to an Intel hex file, the flasher writes in 32-byte lines, so they start ":20".  Is there a switch or other way to persuade the flasher to use 16-byte lines?  Of course I could convert later, but would just rather have it the way I want it to begin with.  If not in 1.3.3, is there a later version that provides this option?
