Permission Owner - How to add multiple owners from a csv file.

I am loading permissions from a CSV file. One of the columns is owners which is mapped to Permisison Owner fields with Identity attribute as Email.

I am trying to add multiple owners for permission from the CSV file. In the owner column in CSV, I tried this by giving emails separated by semicolon, and comma with whole string in double quotes.

These are the options I tried;


In both cases, it is taking only the first email id as the owner.

Is it allowed to give multiple email IDs as an input value for the owner? If so how we can define it in a CSV file?

I am trying to avoid the group as the input value.

Thanks in advance for the help.
