No, best as I recall you get to the point you effectively pick a time slot (based on the chosen "first shot date")
before putting all your info in.
Completely different from the "normal" process.
fwiw, The Spousal Unit had one of her friends come over the house and she got her a confirmed reservation. This lady needed to get a specific day so she could get a ride to Gillette and back (she did not want to impose that on my wife) and didn't get the gist that the very first step affects the offered reservation date: she kept picking "Feb 3" as her "first vaccination date" which firmly put her into a March 3 reservation date. All she had to do was pick a later date for her "first" and the site would jump 4 weeks ahead. Carol got it done
I just heard on the local news that the state is trying to straighten out the mass vaccination reservation system, but I would not hold my breath, as the crux of the "it was there but now it's gone" reservations is apparently due to cross-system communications between multiple entities to schedule each shot. The scope of that sounds too broad for any easy fix...
Cheers!
[edit] btw, the mentioned lady actually did grab a spot and got the email confirmation but it was an incompatible date. My wife helped her cancel that reservation and grab a later date that worked for her. So mistakes can be fixed
