Plan a Getaway - Specific Targets for Interaction

The controls for Plan a Getaway let us select sim interactions such as flirt, makeout, woohoo, but it doesn't let us select target sims, groups, or objects, and this is a problem for storytellers if they want to host events where sims who have special relationships participate in romantic activities. For example, when I create a waltz event, I want my sims to choose only their romantic partners for slow dance and waltz.

It would be greatly appreciated if you could add an option to set interaction targets for custom roles, such other roles, a list of sims not necessarily in a custom role, or a specific sim. Even another role as target would be useful, but preferrably lists of specific sims as targets.
