Is there a way to edit the list of existing data sources when creating a new dataset?

When creating a new dataset, the list of existing or previously created data sources is listed after all the options for creating a new one. Some of these existing data sources are obsolete and I would like to delete them to prevent mistakes going forward from other users selecting one of these obsolete data sources. Is there any way to delete these existing data sources from this list since they are no longer being used or even relevant? Thanks much!

Hi @mkenrich

Currently this is not possible. I can mark it as a feature request!
