Duplicate an exiting program from your own account is not possible.
At least not yet. This is in the roadmap and will be implemented soonish.
But there is a way to do it, if the program is from another user...
If "User A" creates a program, and sends the link to "User B", "User B" will be able to open that program and clone it (with any name).
"User B" can clone the program from "User A" multiple times.
