How do I copy workflows from one project to another?

I’m new to Weweb, and have a very basic question:

How do I copy and paste a workflow from one project to another? I can copy and paste it within the project by clicking on “Copy Workflow” & “Paste Workflow”, but I can’t do it across projects… When I try to copy and paste the individual actions across projects (this seems to be able to do it across projects), it doesn’t copy it completely. Is there a way to just port the entire workflow over?
