Export always exports all columns

Export always exports all columns

Hi,

I am exporting Sprints tickets to cls and only need the following fields
- EPIC
- Item Type
- Release
- 'Release Note External' (which is a custom field)

Unfortunately:

- the file always contains all standard fields
- it does not contain my custom field
- openeng the dialog, it always is reset to 'all fields', which is extra load
