keep track changes

[Raymond]

Dear all experts,

I've a flowchart diagram and need to change contents regularly. My problem
is when I receive some update information and need to update those
flowchart's contents.

Is that possible to keep the history (previous contents of that shape) and
for later reference?

Big Thanks in Advance.

I would try copying to another page as an archive. There is no built-in
feature for this.
