Activity column with multiple week ending schedule dates

Hi,

I have a data set for a commissioning schedule i woud like to get into power bi. I have one column with the activity/task and multiple columns with week ending dates that get filled as job progresses.

Any idea how i can link my Dates table to the Summary table containing Activity/Task Description and Week Ending columns?

The goal is to create a dashboard so when training dates or due dates are coming up, individuals needing to attend training can easily open up dashboard and see dates in a matrix or table type of scenario.

Link to data set below:
