Batch-add books to Shelf

[prohtex]

Describe the feature you'd like

Hello there, after years of suffering with WikiJS, my organization has moved to BookStack and we couldn't be happier! Just about everything is orders-of-magnitude easier and more useful. The performance, in particular, is amazing.

One thing we're missing is a way to batch-add books to Shelves. The process of going into the stack and dragging items over is quite time consuming, and we have a LOT of books.

There are two small changes that I feel would really improve the usefulness of Shelves:

1. Allow the user to assign a book to a Shelf on the Create New Book page. This could be an expandable item such as "Cover image," "Book Tags," with a series of checkboxes.
2. Allow the user to batch assign Books from the Search Results page. For example, we would really like to add all Books with a particular tag to a Shelf. In this workflow, we would search for the tag, and from the results page add them all at once.

Describe the benefits this would bring to existing BookStack users

These changes would greatly benefit users with lots and lots of Books.

Can the goal of this request already be achieved via other means?
