[Cin] Lock an asset within the EDL

My enormous "what I would love to have as UX' is something that is still on my todo list, but I am currently editing (again) a massive project. Now using the method of dailies, which effectively means placing all assets on the same timeline, and cut out the best takes. Since my biggest nemesis still is to sync audio against my videos I wonder if anyone knows if we allow to lock a specific asset (not track) on a fixed position on the timeline. Hence it should never move or be split. -- Stefan
