Wishlist - automatically set the 008 date correctly for a new MARC record

Each MARC template uses an xml record which defines the default tag info to use including the dates.

<?xml version="1.0" encoding="utf-8"?>
<record>
<leader>00620nam a22 i 4500</leader>
<controlfield tag="008">070101s eng d</controlfield>
<datafield tag="010" ind1="" ind2="">
<subfield code="a"></subfield>
</datafield>
<datafield tag="020" ind1="" ind2="">
<subfield code="a"></subfield>
</datafield>

The first six numbers (008/00-05, which currently come up as 070101) are supposed to be the date the file was created in yymmdd format (see https://www.loc.gov/marc/bibliographic/bd008a.html ).

Wishlist request to add a TODAY()-esque function, to automatically complete the date with the date the record is created
