Jon May Makes review for Shopify Flow

My campaigns are simple but I have A LOT of doubt because of the UX. 1. I can't copy a flow with emails. I have to clone an earlier version of the flow and add new email templates every time. The email template doesn't copy the subject so I have to copy that from elsewhere 2. My campaign is dependent upon some values that I wish I could define as variables to use throughout the flow. Here are some examples: email address, discount code(s), url. It would be great if I could also use these variables in the email templates. Then it may be truly a clone and send campaign. As it is now, it's extremely bare bones and took a lot of effort to create a simple 3 email campaign that I repeat monthly.
