It would very useful to have a task in one planner and also visible and manageable in an other planner.
We have one planner for each of our projet and in every project we need to make a request for transport to the supply teams. So we create a task "Transport Project A".
Which allows the project manager to have an overview of his project.
However for the supply departement, it isn't easy to have an overview of all the transport that need to be organized.
Solution 1: we could Copy&keep Synchronized the task in another planner
Solution 2 : one task can be register in more than one planner
-->the supply teams could have much more effective planner for themselves and the project manager will be kept the overview and information on the task
