Saving Master-Detail Columns and Their Order

While using the Master/Detail report, and having rearranged the order of the columns, how can that column order be saved, so that when the saved report is opened, the columns will have that order?

How can columns be removed from the display, and then have that edited set of columns be saved?

Click the top left corner of the grid to remove a column (or to bring it back later)

Click the Save icon at the top to save it. grid preferences are included in the MD file.
