Aggregate Discounts using customizable and bundle product

Hello,

We've a requirement where when customer buy customizable product and add another regular product (bolt on product) then apply x % discount on bolt on product.

e.g when customer buy customizable product A and add product of type bundle product B then apply 5% discount on product B

I think we could do using Aggregate Discounts but can we use customizable  and bundle product in Aggregate Discounts?

Note - It doesn't matter how customer has configured customizable product. As long as customizable product A exist with bundle product B on quote, we'll have to apply 5% discount on bundle B

Appreciate any help.
