As far as I know, it is not possible, if you make a "new" entry.
You could configure the elog, to always PRESET an atribute, but then it is always the same, not the last.
I think the "duplicate" entry function could provide you partly with the functionality you want, as it copies all old values into a new entry.
I am using elog as an observation log for amateur astronomy. I have a form configured, but I would like to know if it is possible to make certain fields persist across new entries.
What I mean is this:
When I make an new observation, I select a value for sky conditions (say.. "1"). When I make another observation, "1" is already selected.
Is this possible? If so, how?
