Normally, you would open a specific task, and multi-home it into a second project. That workflow works well.
Here’s a new workflow I’m suggesting:
- From the project page, choose “add task from another project”
- Search for a task that already exists
- It’s multi-homed into the project you are looking at
Rationale: Sometimes you realize you want to multi-home a task when you’re looking at a related project, rather than creating the task itself. It’s a bit inefficient to leave the project you’re working on to find the task you want to multi-home.
