Dynamic table columns based on slicer selection

I am creating a power bi report that is filtered by Month, Year, Employee, Certification.  The first column of the table is Day (of the month) that shows even days that do not have data, so I have every day of the month represented.  When Employee (and year) are selected, this will filter the Certification slicer.  When that Certification is selected, there can be a number of different tasks I need to show based on that cert.  I have some very rough sample data here that shows only 5 certs and their related tasks.  Each cert can have a different number of tasks.  The data source that is coming in is pretty flat (I have no control over it) with 32 columns just for the Task and I know, not the cleanest way to build, but I did not author the data source.  Is there a way to dynamically show the columns based on the cert selection?  Thanks for the information

UPDATE:  I am trying to do the pivot of the columns, however, this breaks the ID column, which has a one to many relationship with other tables.
