How build different product/odm image for different SKU in one build.

Dear all, 

I have read:

1. Building OTA Packages

2. Product Partitions

3. ODM Partitions

I know that product and odm is updatable by OTA. And 

Android 9 added support for building product partitions, enabling the use of a single system image for multiple software SKUs supplied by different product.img images. While the product partition is intended for software SKUs, the odm partition is intended for hardware SKUs.

So how to build different product/odm image for different SKU in one build？And how to build one incremental ota packages for different SKU? Building OTA Packages has mention that using dynamic fingerprints. But it use the same sku image and import different prop file, not different odm images for different sku.
