Spelling / WordComplete

EmEditor has "Restore Deleted String" command. Is it possible to (add an option to) exempt the WordComplete/SpellingSuggestion deletion from being the "Deleted String"?

Suggestion: (If issue E will be implemented in the future.) Need a way to add user word forcedly. Or make the "Add to Dictionary" command available all the time. Reason: For example, the default dictionary has "alway" but has no "always"; has "property" but has no "properties".
