How do I make it so that authenticated participants (i.e., from a contact list) can use the same link (with an embedded userid on the end) to do multiple responses? More specifically, 

Imagine survey “mood” is presented on multiple different days across several weeks. The same survey is used each time (i.e., the URL does not change) and the userid suffix is added in order to authenticate. So, participant 11002 would do “mood” survey on days 2, 4, 6, 8, 10, 12, & 14. 

Would adding another suffix work? 

For example, adding a “wave = 1” for the URL on day 2 and “wave = 2” for the URL on day 4… I just don’t want to have participants receive a message saying that they have already completed the survey (which we have on purpose for other (not “mood”) surveys in the study).
