Improve mapping capabilities for "Idea category" custom field.

You can add a custom field on epics, features, etc. for "Idea categories". When an idea is promoted, the idea's category will be copied to the epic or feature automatically.

This can be mapped one-way from Aha! to Jira to a text field.

However, if you try to map this to a multi-select type of field in Jira, you can't configure what categories in Aha! map to the field options in Jira, so updates to this field don't work. Also, updates from Jira to Aha! will not work.

This necessitates the need for a separate custom field that is not tied to the idea category, so it can be mapped to Jira two-ways.

Support the "idea categories" custom field with a two-way integration with multi-select fields in Jira.
