Hello,
Annotation graphics cannot have phase assigned to them, only model elements can have phase assigned. Either way you could do it by making a new type to show/hide this based on what you select. Not as ideal since you'd have to manually change, but here's how you could do it:
- Edit the family to add a new Yes/No parameter
- Click on filled region (or whatever you want in family to be hidden or shown based on type)
- Click on the = button right of Visible, then assign that to the parameter you just created
- Then load family into project, and make a new type that has visibility toggled how you want it to be
