Custom button with multiple command options

I would like to create a custom button with a drop down of multiple commands. For example, I would like to create a button for my TV menu controls to active the sleep timer while I’m watching my TiVo. I would like to add the commands of home, select, cursor up, down, left & right. I know there are default drop downs on the virtual remotes for input, format, etc. Are these drop down buttons only available for toggled commands? My biggest feature request (which I’ve mentioned in the request forum) would be an integrated sleep timer function within an activity. This is the feature I miss the most from my Harmony 900. Are there any plans for this in a future update?
