Hello,
maybe there is a solution using the panel functions.
Anyhow, I can suggest the following workaroud:
You build one survey, with three groups of questions.
With a filter for each group.
the filter would be based on time (use the function mktime and compare a fixed date determining if the group is available for answers.
