So the batch edit allows us guess which dates in the future we want for the "available from" and "available until" date. However, there are often assignments added during the course. When I import the course, the dates don't match, so using the BATCH doesn't work. Moreover, EMPTY dates will not work with the BATCH option. I find the current system extremely difficult, unnecessarily time consuming, and mostly useless. What we need is a system that allows to adjust COLUMNS at once, and this needs to apply to empty dates as well.
HOW can we BOTH "set" and "edit" old dates and empty dates COLUMN BY COLUMN. i.e., if we want to edit ONLY the "available from" dates on every assignment all at once, how can we do that, aside from copy and pasting a date and laboriously going assignment by assignment? Also, if we want to edit ONLY the "available until" dates on every assignment all at once, how can we do that, aside from copy and pasting a date and laboriously going assignment by assignment?
