Setting Up a multi-session event

Hi. I have been a Constant Contact user on and off for many years. I have a decent understanding and usage of event, fundraising and membership management software tools. I just recently signed up to help migrate a membership group I am on the board of to CC. Our first event is a Photo Fundraiser, which means a 2-day event with various sessions (time slots) that constituents need to choose from. I did discuss this with your tech support team, and the work around is less than optimal. I understand that CC is working on a big Event and Email update, so I am hopeful that this type of event will be addressed. 2 BIG issues with how it is now 1.)Issue, I had to duplicate the event 20 times to allow for sign-ups of a specific time slot. Then I set up an email, had to link each event with it's time slot to a button on the email. So when ppl sign up they can't tell which event is full and are clicking around. Super frustrating for the end user and super time-consuming for me.  2.) Issue, we have to use our Church's payment system, and I can not include a button in the Event page or even in the registration confirmation, so I am instructing them to come back to the email (after registering) to pay. Equally frustrating and difficult to manage.  I am more than happy to discuss this further with you. Thank you
