Creation of friends groups for custom privacy settings

Is there a way or maybe there is a plan to make this feature, to set different friends groups, so I could assign different privacy settings for each activity for them. For example, I want to share my walk with one group (my mom and a spouse), but not with the other (coworker, acquaintance). So when i choose Who can view an activity, besides "only me", "everyone ", "my connections", to also have custom options, for example "family", "work", "friends".
