Selecting and Deselecting Fields

I am trying to import a file to MySql.

My database has 70 fields.
Selecting and deselecting the fields is very tedious.
Each field needs to be clicked.

Furthermore, once I can back to the import function again, it has forgotten which fields I selected.
I have to deselect all the fields once again.

I think they could be a better way to do the selection and deselection of the fields.

Feel free to post suggestions here!

Here is a suggestion.

If I hold the left mouse button down and drag the mouse down all the fields they should delect.
(i.e. toggle)

I should not have to click on each field but rather just drag the mouse over the field with the left mouse button held down.

Also, the status of the field (select/deselected) should be stored.

Another suggestion would be to look in the first row and if any data matches a field name than too automatically select that field name. (i.e. default for each field is deselected).

For example, if the first line had:

Index, Lesson, English, German

Then the fields "Index", "Lesson", "English", "German" would be selected and everything else would be deselected.
