Drag mono and drop as stereo

In Wavelab 6 there was the option to drag a mono file and drop it as stereo if you press ctrl during dropping. This does not work anymore in WL7. Does this option still exist, maybe with another key?

It is there, but the key had to be changed, for Mac compatibility. It is now Alt + Ctrl

Thanks PG, that works. In WL6 the little waveform symbol next to the cursor changed from mono to stereo when I pressed ctrl (now alt+ctrl). This was helpful. I had tested alt+ctrl in WL7 before but thought it didn’t work because the waveform symbol did not switch to stereo.
Anyway, great that this option still exists.
