Convert comments to end notes in compiling for MMD/LaTeX?

I am back at having a go at using MMD/LaTeX/LyX instead of Nisus for formatting and printing documents. In formatting and printing prior to final draft stage it would be helpful to be able to convert Scrivener comments to endnotes the way it is in Nisus.

That appears not to be possible at present. Am I right about that? If so, is it something that could be added in future Scrivener updates?

Thanks,
