For sure possible, and i saw newer products with this Options too. Maybe a closer to productpage would help to find it. We did that a Long time ago too https://www.renderosity.com/mod/bcs/straightpantzz-for-m4/77367/

Honestly, i always forget to add this Feature. I´m happy when i have all Morph in , that a Cloth Needs. Should write it down for the next product ;-)
