Install packages with specific versions in single transaction

[Daniil]

Hello.

As documentation says I can write construction like that:

apt: name={{ item }} state=present
  with_items:
    - package1
    - package2

and have single transaction to package management system:

ok: [foo.bar] => (item=package1,package2)

My question is how can I install multiple (many in fact) packages with specific versions still in one transaction?

Approach with 'with_dict' loop

- apt: name={{ item.key }}={{ item.value }} state=present
  with_dict: "{{many_many_packages}}"

 still generates one command per key in dictionary.

Thank in advance, Daniil.
