Change defaults for annotations, esp. lines?

Has a way been developed yet to set defaults in annotations on PDFs? I have to draw hundreds of lines in dozens of PDFs and each time, I have to manually change the line so it doesn’t have an arrow end and is thinner, which adds a great deal of time to this task. How can I do this? Thanks.

No, this is not currently possible. It may be a feature in a future release.

The last used width should already be remembered, the next release will also remember the last used arrow style.
