I don’t know how it works or how configurable it is, but have you considered “Find Similar” in Izotope RX?
I don’t know of anything in Wavelab specifically for this. Unless there are tiny digital dropouts or sharp waveform discontinuity at the in and out points where the card skipped. Wavelab Global Analysis Errors/Glitches will find those. I usually set for high threshold and sensitivity (like 99 and 99), but you could try lower as well, although if you do you might get a lot of false positives.
edit: then again “Find Similar” probably requires an initial selection in order to find similar, so possibly wouldn’t be useful at all. But I haven’t used it so don’t know what it can do beyond that.
