Symlinks in Capistrano?

I have a few projects with large directories (say, user-uploaded files)
that
make using Capistrano a bit awkward. However, I suspect that I may have
reached the “write a custom task” level.

(I suppose I’m just thinking out loud, here…)

It seems as though I’d want this directories symlinked in /shared…
Maybe
there’s a way to extend the ‘symlink’ task to do this… ?
