We use a custom field in the idea portal to indicate which version of our software that an idea was implemented in. Some of our customers have expressed a desire to be able to filter ideas by which version they were implemented in. E.g. select to see all ideas implemented in version 10.7 of our product. In order to allow that we would need a way to enable a filter based on our custom version number field.
This would be very helpful to track and filter by which customers have requested specific features.
