Publish Columns setting gets changed by import of competitors in csv file

I wish to publish updated competitor lists as the entries arrive.

Each time entries are imported from a csv file the column settings get changed to yes for display and publish of all columns imported.

The published competitor list should contain only a few columns. It is too time-consuming to change those settings every time competitors are added.

Is there any way to set the columns for a competitor list or to stop the publish columns setting from being changed by an import?
