Hi,
Then I create an Idea for particular product can I have more configuration options on initial Create Idea page, like
Select Release
Select Subscribers
Select Watchers
Etc.
As now I have to create an Idea first and then configure all those option which is not very convenient.
The status of this idea was out of date. It is now possible to customize the create forms throughout Aha! This article explains what is possible in more detail.
