Proxy media not generated for all selected subclips

Bug found, to reproduce:

1. Create three subclips from the same media.
2. Select them and right click and then select "Generate Proxy Media"

Expected:
Proxy media is generated for all selected subclips.

Actual:
Proxy media is only generated for one of the subclips.

I saw that this has been reported by others before. It would be immensely helpful if this could be fixed since generating proxy media from the entire source clips takes much longer than doing it from the sun clips.

Any comment from BMD?
