additional question type

Hi guys, We have this course with questions. 1 question involves drawing a network topology. Now we have set this question as "file upload question". The user needs to draw something in e.g. paint and upload the jpg. The course admin will look at the upload and assign points. This is not the most convenient way. Is there some question type available where the user can draw in a white space on the website itself? Thanks in advance. Greetings Will
