Enlace general webapp

So far the links to the webapp are customized for each reservation but we think it would also be a good idea that there is a generic link that we can send and the customer, for example by adding your day of arrival and the confirmation number of the reservation can access your reservation and can make the online check-in and payment of the reservation. Since we could automate the sending of this generic link and it would not be necessary to go reservation by reservation sending the link of each one by whatsapp.
