Hi @Anonymous ,
It is not possible to select property from the CVS table and add it on an Apply to each action.
Please consider using action Select to generate an array of selected items, then select properties from the array and use it on an Apply to each action.
Besides, when using Select action, we could add, remove, or rename elements in each object in an array.
I have made an example for your reference.

Best regards,
Mabel
