Magnitude estimation paradigm

Hello psychopy experts!

I’m new to psychopy (and not a python expert), and I’m setting up a magnitude estimation experiment. Is it possible to record magnitude estimation data directly from the participant in psychopy? What I envision is a sort of a “form/frame/entry box” that pops up on the screen, and participants enter their rating. I suppose it’ll have to be “editable,” so that they can fix typo’s. Is this something that can be implemented in psychopy?

Thank you in advance!
