Add popup activites to Action Panel Dropdown list?

In V5, is there anyway to have popup activities appear in the action panel activity drop down list? Currently it seems that you have to use the dropdown to go back to the room’s activity list to select a popup activity and then re-select the current activity to get back to it. Seems to defeat one of the primary reasons for having a popup activity.

I know in V4.5 you could have added a custom button to call the popup activity. But until you can again edit remotes in V5, this seems like a reasonable workaround.

Or am I missing something?
