Questionnaire before splash page

Hello, 

Is is possible to configure splash page to collect some customer data (eg: email, mobile number, service feedback question) before authentication ? 

Deployment: cnMaestro on premises and few E series enterpise APs. 

Thank you. 

At the moment the only way to do this is with the use of a third party captive protal (Encapto for example).

I can see you've submitted it as an idea, it would be a feature I would like to see added in the future... fingers crossed!
