How do you lengthen the recording time in Kid Pix 4? It is too short for our 2nd graders! Help!

Hi I have a group of 2nd graders trying to record sentences into their KidPix graphics, and the time allotted for their recording is way too short. They are forced to record multiple blocks, which gets confusing for them.

Does anyone know how to either lengthen the recording time or another solution?

THank you!
