Sign Up Card In Editor Functionality

I really love the sign up card, and would love to use it. But I really with it had all the functionality or the option to add the same functionality as the regular sign up portal that is included into the themes.

Without the ability to control the welcome email to that card, they have no way to know they need to now choose their newsletters, and also they have no way to be redirected to a page that shows the different membership tiers and paid tiers.

I am unsure as to what they are even signing up for, since there is no way for them to choose a newsletter to subscribe to and it seems that it is simply adding a new member to your website who is not subscribed to anything. If I am wrong, when are they given the choice to select a newsletter? And how would you even market them if they’re not signing up for a newsletter. It seems that you would have to set up an automation using a 3rd party and target the label that you choose to add to those sign ups.

Not sure if this belongs, here. But it is an idea that I would really love to see in the event I am correct on my understanding of how the sign up card currently works.
