Force Transitive Dependencies

Referencing this answer: Problem with transitive dependencies - #4 by cocreature

It would be great if i could force expose all packages within a dar.

Suppose I had a dar (main.dar) with 10 sub dars (one,dar, two.dar,…,ten.dar) packaged inside it, then my daml.yaml would look like this (if i wanted to access the templates inside the sub dars:

data-dependencies:
  - <path_to_main.dar>
build-options:
 - --package=one-0.0.0
 - --package=two-0.0.0
 - --package=three-0.0.0
....
........
 - --package=ten-0.0.0

Ideally would be nice to be able to do the following,

data-dependencies:
  - <path_to_main.dar>
build-options:
  - --unpack-packages=main-0.0.0

This is useful as splitting of dars and packaging them as a bundle has advantages when upgrading and deploying
