Is it currently possible to add custom dimensions at the product level in GA4, so that they can be used for reporting?
For instance if I send data that looks like this:
event: 'purchase',
value: 500,
items: [
{
item_id: 12345,
item_name: "New Book",
item_author: "John Smith"
}
]
Is there any way to configure GA4 so that I can see the item_author field in product reports? I've seen as late as October 2021 that there is no support for this, but wondered if this had changed, or if Google had published any info as to whether this WILL happen and if so WHEN it will happen?
