I'm currently in the process of migrating over multiple characters from elsewhere, and a thing that is sorely needed for someone in my situation is the ability to copy over interests, kinks and such from one character to another. I have around twenty characters I am aiming to create, and it is going to be an absolute pain to manually choose every single kink over again for all of them.
As my interests tend to be the same between characters, with minor variation, so it would be much better if I could copy over interests from one character to another and then apply the small variations afterwards.
