I use orgmode capturing to schedule events. The date ends up going
in to three places: since my agenda file has things scheduled in a
tree, it asks where in the tree to put it. Then it asks, what
regular date to insert for the schedule; then it asks what date to
use for the deadline. I use deadlines because of how they function
in orgmode, and I use regular dates so they are exported properly
for Google Calendar. But how can I cause two or even all three of
these to use the answer from just one prompting of the date, so I
don't have to specify so many times?
