Filter specific value on a concatenate field in DAX

I'm not expert in DAX and Power Query language and I would need help.

I have a table similar to the following:

Item1 Item2 Item3 Item4 Conc_2-4
A     B     C     D     B,C,D
F     G     H     I     G,H,I
L     M     G     C     M,G,C
A     H     D     R     H,D,R

In my report I would like to display a table where there are only the first 4 columns (without the column Conc_2-4), but I would like to be able to filter the table through the column Conc_2-4, without this being displayed in the report.

In other words, I would like to have the distinct values of the items in the filter and when I filter a certain item, the result should return all rows in which this item is present in the columns Item2, Item3, Item4 independently from the position.

EXAMPLE

If in my report I filter the item H, the resulting table in my report should be as follows:

Item1 Item2 Item3 Item4
F     G     H     I
A     H     D     R

Does anyone know how to solve the problem? Maybe using Power Query?

Thanks for any suggestions
