I've been struggling with this myself. It's incredible that something so simple can't be accomplished by a regular user. I have hundreds of transactions that I wished I could just check and reclassify, but the only way for me to know which, is by looking at the Description field - WHICH IS NOT PRESENT IN THE EXPENSE TRANSACTIONS LIST where you could potentially do batch reclassifying. So I figured I would just do an ADVANCED SEARCH and look for my transactions (by Description), but once they all show up, THERE'S NO BATCH ACTION YOU CAN DO WITH IT (you can't even select them other than opening them one by one). It is immensely frustrating.
