We are a team with several projects going at any given time. Currently I have multiple timelines spread out into multiple docs. I can copy and paste them into one "master" doc, but anytime I have to make a change to a timeline, it would force me to do that on multiple docs.
This is also a similar case with out team when it pertains to tasks. When I assign a team member a task in a Paper Doc ... there is no way for me to have a master list of who is doing what. I have to dive into each individual doc to see who is assigned to certain tasks.
