Hi @CopperNu.
Formal support for MSFS by Microsoft / Asobo is provided by the Zendesk website, where users can open support tickets.
These forums are an environment for users to:
- Discuss Microsoft Flight Simulator related topics (Discussion Hub)
- Help each other out (User Support Hub)
- File bugs & wishes (Bug Reporting Hub & Official Microsoft Flight Simulator > Wishlist)
- Engage with the community (Community Content Hangar)
- And to provide a platform for user feedback on the sim ( Official Microsoft Flight Simulator > Polls & Feedback )
I don’t user the planner, so do not have the answer to your question, but feel free to create a new wish for this functionality (we can always post the solution to the wish & close it if the functionality exists).
Thanks!
Edit: A wish that may cover what you are asking for was recently created:
