Downgrading packages (with dependencies)

[Lukas Linhart <lukas.linhart@centrumholdings.com>]

Hi,

we're building packages with concept of "metapackage": package whose only 
purpose is to specify particular versions it depends on.

Problem is, we'd like to be able to downgrade. However. I did not found the 
option to "force download in dependency chain"; when metapackage is being 
downgraded, all dependencies forced to download must be specified on command 
line (with version to download to).

This is very annoying and yields whole downgrade concept unusable.

Is there any way to force said behavior or work around it?

Thanks,

Almad
