hg copy specifying a source rev ?

[Robert Altman]

Is there a way to use hg copy and specify a source revision?

For instance: given a file "text1", with some revisions (1, 2, 3, 4).
After revision 4, I want to fork text2 using text1, rev 2, as a
starting point.
text1 history: current -> 4 -> 3 -> 2 -> 1
text2 history: current -> 2 -> 1

You can checkout a changeset containing "revision 2" of text1, copy it,
then merge with your current changeset.

Otherwise, no: Mercurial intentionally completely internalizes the
concept of file-level revisions because they're generally completely
secondary to the changeset revision graph.
