Change matrix column header dependent on drilldown

Is it possible to change the column headers in a matrix depending on the lvl you have drilldown?

In the matrix you can see all the deadlines for all the orders which is important when you drilldown to the individual orders, but when you are looking at all the ordres together, Power BI shows the first deadline of all the orders, which is not relevant, so I was woundering if it is possible to hide it until you drill down to the individual orders?

Abother colum shows a list of the sum of active orderes, which is important to show when you are looking at all the orders, but when you look at the individual orders it is just a list of 1's. So I was woundering if it is possible to hide it when you drilldown?

The two pictures show which colums I wish to hide.
