MySQL insert usage when copying data

Hello everyone,

I have 4 tables that hold information that all relate back to each
other. I would like to copy the information for one set of data (like
a copy/paste function in common editors), while also maintaining the
relations. Is there an easy way to do this in MySQL? Functions, or
anything of the like to ensure that all the information is properly
maintained?

Here's a breakdown:
Programs (what I want to copy):
prog_id, prog_name, prog_requirements

Requirements (tied to Programs) (many to one):
req_prog_id (tie), req_id, req_name_ req_requirements

Groups (tied to Requirements) (many to one):
grp_req_id (tie), grp_id, grp_name, grp_requirements

Data (tied to Groups and Requirements) (very many to one):
data_req_id (tie), data_grp_id (tie), data_id, data_name,
data_information

Any ideas?

For those that just want to question my intentions, here is why I want
to copy an entire Program. Whenever the Data changes over time, a new
program needs to be built to show those changes. There is a bit of
initial work that goes into building a program, so to rebuild ALL that
information is extremely time consuming. The goal is to copy the
program and make the changes to the new one rather than rebuilding
everything.

Thanks for your input/advice,
