Actual date and time in templates

I’d like to have a template with actual date and time in the first line. Inserting date and time by menu, date and time are not actual using this template. Will say, date and time should be a macro. How can I realize this?

Hello,
we don’t support macros at the moment. But the support is already on our official feature requests list and we will consider that to one of the future versions/updated.
