Adding multiple columns in a table using one node.

Hello Knime community

I have result of pivot node after preforming some calculations using different nodes. I want to add column1, column2 and column3 in new column and mean of column4 and column 5 in another new column. Is there any node which can add two new columns by performing the above said operations.

I have used different odes but all of them allow one operation at one time.

Regards.
