Newbie question, LLC-DRAM interface

Out of curiosity, is there a mechanism in the Last Layer memory cache to save together all modified cache lines from a DDR4 page (see everything-you-always-wanted-to-know-about-sdram-memory-but-were-afraid-to-ask)?
Obviously complex to implement, but probably would be quite efficient (not re-opening multiple times the DDR4 page for saving another dirty 64 bytes processor cache-line)?
Or is it already done on every usual processors?

Etienne.
