It would be very handy to add a individual batch process-form in admin list, (like in com_content):

-providing in the JCC interface for a list-field the option: "Add to batch processing"

So in the built component:
-there is a button created named "Batch" in admin listview
-after ticking several items and clicking on "Batch"
-a modal window opens and the formerly added list-fields showing up for batch processing the ticked items.

I would appreciate such a function a lot because I need it for my component .
As I'm just a hobby programmer this kind of thing is really challenging to me and takes a lot of time.
