Query regarding the use of wic image during device upgrades


I have been using wic image format lately to create partitioned image for my device.
I was wondering if wic image format can also be used during the device upgrade scenarios?
After using wic image, I have an impression that it is mainly used for initially writing the wic image to sdcard/eMMC but does not support all the thinkable use cases related to device upgrade.
As in, for example, can we selectively upgrade any single partition in the device using the wic image?
It would be really helpful if I can get some references or pointers on this topic.
