On the fold3 website, you can find in the MACR area daily lists of German crash reports, listing USAAF but also RAF and other Western Allies. On the July 1944 file, there is (in the early hours of the 7th) a series of Allied bombers in Austria: each entry as a location, a time and a report code (ME xxx or KSE xxx), but for these entries there is no serial, as it is the case for other losses:

Hope it helps
Edited: the above crash reports lists are available on the fold3 website for 1943 (one file, covering the whole year), 1944 (one file per month) and 1945 (one file, covering up to March 1945 with less and less records). They are not complete but are still very useful.
