Hello
I have created a survey. I need to figure out how I can provide a user a link and they can use it for multiples response. A key factor is that the user may have 3-5 open surveys (in progress) at one time. What I am running into is no matter what I do when I provide a link to a user they start the survey, if they complete and submit the survey and return to the original link it starts a new survey (which is okay). The issue is they may start the survey (for a sub-user/customer) and only partially finish but then need to start a another survey or two for another sub-user/customer. This esentiually means that a user has 3-4 in progress surveys and may need to return to each of those specifically at different times to complete/submit. Is this possible and how is it done? How would a user know which survey is for a specific sub-user/customer.
To help understand the situation here is an example.
I email a distributor a survey link. The distributor has multiple end-customer that will be providing information to the distributor to fill out the survey. That distributor may have multiple open/pending/in progress surveys for multiple customers. How does the distributor keep track of what link is for what customer and how do we set this up so they can have multiple open/in progress links?

Thank you
