It's called "upgradeDepends" and you give it a import_profile and an
explicit list of import_steps to run.

It was introduced in GS 1.5 as:

"Add <genericsetup:upgradeDepends> ZCML tag; defines a specialized
upgrade step that re-applies one or more import steps from a GS
profile during an upgrade process"
