Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hi Evangelos,
Welcome to the Microsoft Q&A forum.
At the moment, I have not found any official information indicating that Planner will introduce a feature that allows users to copy and paste screenshots.
I have noticed that quite a few other users are also interested in having a feature similar to the one you mentioned.
You can share your feedback and submit this feature suggestion to the Planner development team through the official Feedback page below:

I look forward to continuing the conversation.
