Is it possible to copy additional details of the last activity that happened on an Account (or any of its Contacts) to fields on the Account? I know there's the Last Activity field that shows the date for the latest activity, but I'd like to pull in the subject and assigned owner as well.
Can this be achieved anyway other than a trigger?
With Spring15 the idea to allow last activity date to kick of workflows is marked as delivered, by process builder.

I think you would need to use pb to launch a headless flow when last activity date is changed. Don't think it would be possible w pb by itself.
The flow could lookup the activity where due date == last activity date (somewhat tricky given how last activity date evaluates contacts, opps, etc, but feasible) and then write the values to account.
Thinking out loud, it may be easier actually to just use pb and flow on activity as you can easily lookup all activities with a given account id, sort by due date, and write the values from the most recent activity to the account.
Either way there should be a declarative option using flow and pb.
