I've been reading the Pega documentation on how to use Secure Data Transfer service in the Pega Cloud to transfer files.  We would like to setup a couple inbound file feeds using this.  From the documentation it isn't clear if we have to specify IP addresses to allow outside systems to connect, if we can use a DNS name, or if they can be left blank.  Are wildcards available to use to specify ranges?  That part of the documentation isn't completely clear.

It sounds like to set up each one of the transfers we have to open support tickets with Pega.  Is that going to change in the future to be more self service so we can manage more of our Cloud instance and the movement of files to and from that?
