Content Sharing: Option to share with "Party" instead of Campaign

Request: Can we please get the ability to create a "party" of players (D&D Beyond users, not characters) and share content with them instead of with the "Campaign"?
Explanation/Reason: As I run one campaign currently and wife will soon be running her own campaign: we will have to enable/disable each time one is used. However, both campaigns have the SAME five users, only the role of DM and player is swapped between two users.
