How to get the Trial-flow displayed in sequence of squares?

If this template helps then use it. If not then just delete and start from scratch.

OS (e.g. Win10):
PsychoPy version (e.g. 1.84.x):
Standard Standalone? (y/n) If not then what?:
What are you trying to achieve?: I am trying to get the display of my trial-scheme of the entire experiment I programmed on Builder.

Hello everyone,
I have programmed an entire experiment on Builder and now I would like to get a resuming display of the entire experimental outline in form of a descending sequence of squares (I saw many papers where the trial-scheme is displayed this way): could anyone explain me how to get it?

Thank you a lot in advance!
