Multi-card import?

Question

As far as I understand it, files from only one CF or SD card at a time can be imported through LR. Now that the import speed has improved ("Thank you" to those who worked on that in LR3), I would like to be able to use this feature. However, many of my jobs result in multiple cards because I frequently have multi-camera shoots. If I import only one card at a time, it takes far too long, so I plug in my card readers and use the OS to copy the files to a folder, then import the folder. This works, but I doubt I am the only photographer who has shoots where more than one camera is used, and it would speed up the workflow to be able to import several cards at once through LR.

Well, I seem to have solved the problem. I'm not sure how it happened, but a stray character got into the rename I had set up upon import.
On the card, the pics are named IMG_XXXX.CR2. I have Paerture rename them with a custom name, the date, and a sequence number. Originally, the file names would end up looking like this:
Parker_River_NWR__ 2011-12-24/2.CR2
with the "Parker_River_NWR_" being the "custom name", the date following, and the serial separated by a slash. Worked fine for a year and more.
I must have fat-fingered the custom name on one import, as I got all sorts of oddball characters in it recently.
Anyway, I installed Lion, and now, the import was trying to do this:
Parker_River_NWR__ 2011-12-24:2.CR2, with a colon instead of the slash! Funny thing was, I never changed that part of the rename instruction, and when editing it, the slash was still there!
I cleaned up the rename string so the new files look like this:
Great_Swamp_NWR_2012-02-20_2.CR2 using another underscore in place of the slash. In fact, Aperture will not let me put a slash in the renamed file name any longer!
Very weird, but all seems to be running fine now.
