Same subscriber in different lists

Hi, congrats on the plugin. It’s all I wished except for one thing… I’d love to see a menu where I could manage each subscriber profile and assign its email to different lists at the same time.
For example, I need Subscriber 1 to go into list A, B and C without having to go to List Manager and adding the email of this subscriber manually to each list.
Do you have plans to include this in the future or maybe you know a plugin that would accomplish this? Thank you so much!
