[Feature Request] set `$segment` for fetchOperations

Feature Request

What's the feature you think Backpack should have?

I try to explain my situation.

Our admin panel is huge and complex and so we grouped routes. Every controller group has a prefix and a name So we have routes like users/activity/create instead of activity/create and names of users.activity.create instead of activity.create

So in un activity controller we have

CRUD::setRoute(config('backpack.base.route_prefix') . 'users/activity');

But when we use fetchOperations, we loose the name.

we have users/activity/fetch/students named only as activity.fetchStudents

The problem is: we have also an ActivityController under manager (name and prefix). In this 2nd controller, in a different folder and namespace, we CANNOT have another specific fetchStudents function because this will always create a route named activity.fetchStudents

So i think that

1. setupFetchOperation should take in care what setRoute has already setup instead of using only singular entity name as segment
2. a documented way to workarounde this

Have you already implemented a prototype solution, for your own project?

I actually workaround overriding setupFetchOperationRoutes

Do you see this as a core feature or an add-on?

fetch it's already part of pro addon
