SKU-like field for add ons

Hi there,

I was just wondering if it was possible to add an SKU style field to the addons which would be returned in the order item meta data, so that I can assign a number to each addon which matches up with the SKU on our back office system?

For example, a radio box with Label: “Blue” & Sku: “1022” which would return meta similar to this:
[0] => stdClass Object
(
[name] => Which Colour?
[value] => Blue
[sku] => 1022
[price] => 0
[price_original] => 0
[price_type] => fixed
[type_id] => 5
[original_value] => Array
(
[0] => 0
)

[original_index] => 0
[sold_individually] => 0
[calculate_quantity_sum] => 0
[add_on_type] => radio
)

I understand this would likely be a premium feature, and I am ok with that

Thanks in advance,
Ross
