[Beta 2.0.0] Add asset/matrix field without removing previous content

[RichardGG]

Is it possible to update an entry's asset field without removing the previous content?

Here is an example:
I have a set of entries with a unique gallery ID and an asset field

Using my JSON feed, I can update each gallery entry, but the image replaces the previous asset rather than simply adding it to the field.

[ {"gallery_id": 1, "image": "url1.jpg"}, {"gallery_id": 1, "image": "url2.jpg"} ]

Perhaps this could be an alternative import strategy?

Its not currently possible to append content on element fields (Assets, Entries, Matrix, etc). Data will instead entirely replace the content of these fields. I'll look into adding this as an option for each element field, as its not really about the import strategy as a whole.

Sometimes us content creators need to append a value to an existing set of data. This would be super useful.

Poking up this again, my use case is to append array data to a matrix field array on multiple feed runs.

But I would add a unique identifier to each item to check each block so you can update items still, exactly how you do it for the base entry in FeedMe.
