Prospect/target list subpanel

Is it possible to modify the module and sub panel layouts for the target list?

I do not see Prospect Lists or Target lists in Studio to adjust the layout, fields, etc?

Also is there a way to select more than 50 at a time when applying a target list without using SQL i.e. within the list lookup bulk update. It is always resets after applying a bulk update. The goal would be to 1. apply a filter 2. select all in that filter 3. Bulk update to assign target list.
