Cart Transform: Merge - Allow fixed pricing, similar to Update operation. Or allow chaining of Merge → Update operations and vice versa.

[ljclark]

Right now, if we want to merge several products together to create a 'bundle', we can only apply a percentage discount to the price .

It would be great to be able to apply a fixed price to the newly created bundle, rather than only being able to give it a discount - similar to how the update operation works.

Use Case:

Create a Bundle of 5 products for $50.

To achieve this right now, you have to calculate the discount for the combined items to get them priced down to $50. However, this can get inconsistent with higher value bundles/items as you start entering fractional discounts.

It'd be great if you could just say Merge Items 1,2,3,4,5 and update the price to $50.

Also tried to achieve this by chaining a Merge and Update operation, but the update operation can't find the newly created bundle, presumably because the cart transforms use the pre-transformed cart data.
