Batching of requests

[niklas1375]

Enhancement description

I'm trying to create a task with some sub-tasks, which in turn have subtasks. As it is truly annoying to send this many single requests, I would like to see batching as it is available for the Sync API as well.

The problem it solves

Many single small requests cause delays and a single batch request would be faster.

Alternatives

Traversing through ever single step of the tasks to be created - not a nice option.

Use case / screenshots

Adding a task composed of multiple levels e.g. like this:

Base task: Pack bags for roadtrip
├── gear
│   ├── jerry can
│   └── tent
└── clothes
    ├── hat
    ├── pants
    └── shoes
