Thank for the input so far. We are currently automating the way our user is using limesurvey surveys.
Scenario:
User selects a (pre-defined and made by us) survey template to send out. However, some of these surveys require additional information to be included. The user therefor needs to add a/some documents.
In other words, our user don't have access to the backend to attach files. It needs to happen when the user starts to send out a selected survey.
I was thinking of somehow starting the survey with a survey question like: Need to attach file? - With a Yes or No.
When Yes is selected, the user can upload a file and then the file(s) is then uploaded and attached to the outgoing/selected survey when clicking submit.
When No is selected, the survey is sent out after clicking submit (/send/whatever/...)
I think and hope this explains the situation a bit more
