You can sort of do this now:

1. import a DCP.
2. set a start trim on it to remove some content.
3. tick "refer to existing" for video/sound/{subtitle}
4. make DCP and you get a VF with just a CPL which refers to your existing DCP.

In general I think we are missing an option to make just a new CPL/PKL to be combined with existing asset files.

Right, I would make so, if the checkbox was not inactive :)

You are also seeing inactive refer checkboxes?

Yes, exactly about this I'm talking

Hmm.. seems like "refer to..." not working, even if add aditional content

--
upd: in DoM 2.8.0 "refer to..." works. Hmm...

Would you mind giving me a step by step way to reproduce that?

I'm sorry, Carl. I don't know what's going with DoM on my machines, but on pc1 at first was permanently inactive checkbox 'refer to...', and now importing DCP began crashing. Strange, but on pc2 DoM_2.10.4 works fine. Probably I need to make clean install.

I have some thoughts about VF CPL. Let's suppose, that we have a multi-reel DCP feature film. Suppose it is a kind of "Director's cut", and we want to make theatrical version by cutting out extra-content. At the moment we can only trim from start and/or end, but we can't cut something in the middle. I mean it would be nice feature to turn off some reels to skip them in VF DCP. What do you think?
