Customizations for Bundle Products with Custom Pricing

We really need to ability to add Customizations to Bundle Products that employ Custom Pricing.  I need to be able to have a bundle product where a discount code can apply discounts to just a portion of the bundle (one SKU but not the other SKU, for instance).  The product I need this feature for also requires customizations.  So, I am between a rock and a hard place until this feature gets added.
