[BetterRed]

A custom column date can be cleared via the purpose built button that is automatically created in the Bulk MDE Custom Columns tab. But it would suit my purposes better if I could do it via saved Bulk MDE S&R definition. I have two related Bulk S&R definitions - a_move_date, b_counter++ - this would be a third - d_clear date

So I am looking for a Bulk MDE S&R definition to clear a custom date
===============

Has anyone any thoughts on how I could get calibre to support lists of dates? I assume it can't be done without major effort.

So, my idea is to convert a date value into a YYYY-MM-DD formatted string and store that in a tag-like value. Should I ever want use any arithmetic or date template functions I would have to reconvert the strings back to dates.

So the question is - can someone furnish a Bulk MDE definition that will convert a custom date value into to a 'YYYY-MM-DD' string and append it to a custom tag-like value.

I would name the definition c_save_date
================

So now I would have the following definitions -- a_move_date, b_counter++, c_save_date, d_clear date -- that I would execute consecutively in that order.

Failure to execute the definitions in the right order, or inadvertently skipping a step, could result in data loss.

So, it would be useful if I could put those four definitions into a group and execute the group in a single operation, anyone have any thoughts on that?
