Feature summary (what you would like to be able to do and where):
In Extension:Nuke please add a drop-down reason array, similar to (or even reusing) that from Special:Delete. Still allow a free-form reason, still have the free-form reason pre-populated and default.

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
Admins mass deleting pages

Benefits (why should this be implemented?):
Allow easier selection of reasons
