Is there a simple way of attaching my sources to other people in my tree?

For example, a marriage (not an ancestry source). What I do now: I make a proper source citation for one partner, then I go to the other partner, choose source, and copy/paste the detail, date and text from the first one.

Is there a simpler way?
I've got sourced events that I want to attach to 7 or so people ...
