Online check-in from the webApp - Manual registration of minor children

With the entry into force of RD 933/2021, the customer should have the possibility to manually register their minor children, who do not yet have a DNI or passport, as undocumented minors, assign them a usual address, and a relationship, as required by RD 933/2021 on citizen security.

Currently from the webapp online registration I see that it is not possible to do so, if you do not have a scannable document such as a dni or passport.

We are visited by many families with small children and / or babies, it is a real problem that is going to occur very often.
