It would be good to have the functionality of automatically calculating the Target End Dates on issues in Advanced Roadmaps plans based on the logic mentioned below example. If this logic can be made configurable by users based on available options that would be awesome.

Target End Date = Target Start Date + Duration

System should be able to derive and set Target End Date automatically based on Target StartDate + Duration Start date + Duration (customfield defined in weeks or in days).

Currently there is a possibility of achieving these type of requirements using scripted fields (scriptrunner) but since ARJ plans won't support this, users/admins might end up doing lot of manual work. Hence this suggestions request.

Thanks.
