[Koha] Automated Way to Construct Field 2 from Field 1

Hello!

    In our latest exchange, on 2 June 2021 at 17:23 [JST], I received from
you:

    Sorry about that. Have you contacted the administrators to see whether
you can so authorised?

    No, it turns out we did not need this, for MarcEdit's Build a New Field
function worked wonders. All I had to do was to remove the $y subfield from
the newly created 740 fields and reformat the 740 indicators. It took far
less time than painstakingly copying, pasting, and modifying the duplicate
242 into the 740 field record by record -- just about two hours, in fact,
once I figured out the correct procedure, instead of 2-3 days.

    But I have been wondering about MARC modification templates in Koha,
what they are for, why they are needed, how they are useful, etc. I've used
a fair number of ILS's in my day but I don't recall seeing this type of
thing in them. I'm sure there are good solid reasons for them, for I will
be retiring in a year or so, and I don't want to leave features unaddressed
to my surviving and succeeding coworkers when I retire in a year or two.

    Thanks for the help.
