alembic params exposure

Hello there!

I'm messing around with alembic in max 17 and autodesk really set me up. They sayd "Full MXS exposure - range, nth frame exposed" and whats in the reference? (http://help.autodesk.com/view/3DSMAX/2017/ENU/?guid=__files_GUID_5994F8B…) NOTHING :( Is there anybody who knows the exporter/importer parameters?

Thanks!
