Multiple grouped sub-enties

[nahoijtink]

So, let's say you have an entry with multiple items with multiple properties. It would be nice to have the ability to create multiple entries consisting of multiple properties within a single field.

FILES ;Name of the control (label optional)
My file ;Name of the listitem under the control
Size property = 1024 ;Name of a property
My File 2
Size property = 2048
FileType property = mp3
HashValue = FFFFFFFFF

The above is just an illustration of what i mean. Being able to create a field consisting of a list of multiple items, that can have multiple fields/properties.
