Not really an answer to your question - but I kind of figured that out just recently and thought it was interesting > if you use the workspaces (4 bullets in your header that allow you to shift between workspaces), then you have different pinned items on the nav rail for each workspace.  I made one with my favorite developer stuff (automation, protocols, etc.) and one with my favorite operational stuff (e.g. my booking app, my IDP app, etc.).   Just FYI in case it helps for your workflows and ways of using DataMiner.
