How can I display only open initiatives in Parent Link?

[Laura-Nicoleta Iacob]

Hi,

I have the following hierarchy configured in Advanced Roadmaps: Initiative, Feature, Epic, Story, Sub-task.

I would like to deprecate some of the initiatives so that they can no longer be used as Parent Link for features, but I don't want to delete them and keep the values for features that are already done.

I tested changing the status of the Initiative to Done, but, as I also read in the community, this does not work.

Changing the issue type to something else doesn't seem like a solution because it removes the Parent Link of the features.

How can I achieve this? 

Thank you!
