Feature Request: User-defined selection definitions

Currently the selection options are Green Check for "yes", Orange Tilde for "if needed" and Gray X for "no". I'd like to be able to assign different values to the the legend. Ex: Green Check for "available in-person or online", Orange Tilde for "available online only", Gray X for "not available". Another example might be Green Check for "can attend", Orange Tilde for "can host" and Gray X for "cannot attend". I'm sure there are other uses. Please think about it. Thanks.
