Has anyone had any joy writting a custom filter for the Entries table within Contour. Ideally we would like to filter by a value within a specific column. Can you extend the 'Get all ***** records from the last ******' control.

I have also been trying to get a custom export setup that would export to csv based on a column value.

ie. Export all entries where competion id is equal to 2

So far I have been using

public class ExportFacebookCompetitionToExcel : ExportType

Ideally it would display a dropdown that would display all the stored 'CompetitionId' within the contour entry table. The export csv would then be filtered by the given value.

Has anyone implemented anything similar or does any one have any tips/direction?
