I need to create groups or buckets and add things to them

User story: Create a group and add some items to it through a filtered list.

I have a mockup but I am unsure where the list of groups would go in case I'd like to delete them or edit them.

enter image description here

Also, would it make more sense to do a wizard?

1.) Create group name 2.) Add items to group 3.) Save and start over to create second group
