How to add text to MD trajectory?

Dear all,

I'm wondering if there is a way to display a text in the trajectory main window (not in the text area below which is simple). To be specific, I need to show and continuously update the time and temperature in 3D atomistic document window

for each frame while playing an MD trajectory. Furthermore, I want this information to be displayed in the movie of the trajectory which will be saved. I don't know if it can be done without scripting or only with scripting or there is no way at all and will appreciate any suggestions.

Thank you.
