Can we please get an option to paste plain text without formatting in the agenda ?

Hello, I'm very fond of Thunderbird (using it only for agenda, but a lot) and I think that a new practical function would be to be able to paste plain text (= without formatting) with the right click of the mouse into an agenda cell. As I add a lot of events and text into the agenda cells directly from websites or documents, I'm always getting the original formatting that I don't need and can look quite bizarre. Plain text could harmonize everything. I know I could select the text and reformat it in Thunderbird but it's adding unnecessary steps. Thanks in advance for the consideration of my proposal, thank you developers, and have a good day !
