Good day!
Is it possible to transfer a phone number into a questionnaire in LS, for example this type:
http:? // Link phone = 89161234567
?

And the second question:
is it possible to generate a unique link for each questionnaire?
I.e. . If I stopped filling the questionnaire on a certain question and copied /saved the link, then it would be possible to open the link the next day right at the exact question I stopped.

Please refer to the manual:

2) Enable token-based response persistence - manual.limesurvey.org/Survey_settings#Tokens
