Bulk Interest Add?

Hello Tessitura friends,

It's me again.

Thanks to another Tessitura user, I found the manage attributes utility for our monthly mailing list.

Unfortunately, I've realized that we actually need to bulk add interests to our current members, so they have the option of deselecting the interest in the future if they no longer wish to receive the monthly email. This would be a one-time need, as new members are presented with the mailing list options when they sign up. Is there anything out of the box for adding interests to constituent accounts

Thank you!
