Is it possible to rearrange the classes columns in an income statement depending on activity or recent date with activity?

On the image above, I chose the Class as a column. What we need is to have the classes in order depending on which has recent activity. Right now, it is showing in alphabetical order. So far I am not getting any luck trying to replicate what the client needs.
Solution:
The ability to arrange the columns in Financial Reports in accordance with own preference instead of alphabetical order is still a system limitation.
