My sub contractor builds a gantt chart in excel. I have uploaded this into Asana and created tasks and subtasks and a Baseline.
I want to upload the updated excel Gantt chart, but it just creates duplication of the tasks and subtasks. Is there a way for the second upload to just update the dates, so the original baseline is maintained and there is no duplication of fields?
I am also storing information against each task, so I want to retain this information and only update the dates as the project is moving.
