Matrix total not all columns

[azaterol]

Hello everyone,

suppose you have a matrix containing numbers and text fields. With the numbers, it's good that you can see the total. In the case of text I would like to avoid them. You can choose between an earlier entry or a later entry. But what if you don't want to have an entry in the Total line under the text field?

Is there a function for the matrix to exclude certain columns from the total?
