I do something similar but use a perspective to view the Project. I actually do this for my daily and weekly review checklists.

My checklists are daily or weekly repeating lists, Using the daily one as an example I have a series of actions to work through but only want to see them one at a time in the correct order.

To create the checklist Perspective, I focus on the Daily Checklist Project and have the Availability set to next action.

In the project I only have the main Project having a start and finish date. I use three sub projects running throughout the day.
1. Morning Checklst
2. Late Afternoon Review Checklist
3. Evening Planning Checklist

all three sub projects are set to run in parallel but each has a different start and end times so become available at different times of day. Each subproject is then made up of various individual sequential actions. These are then fed to me one at a time via the perspective. As I mark one off the next action appears. When all the sub actions are completed, with say the Morning Checklist, the checklist itself is automatically marked complete and triggers the whole sub project to repeat. (ie via Inspector - Mark complete when completing last action)
The repeat then causes the subproject to reappear tomorrow.
In the afternoon the same perspective then gets populated by my afternoon review checklist, again one item at a time.

My morning list is available from midnight to 11am but I usually have it done by 8:30am It will then remain empty until the afternoon one triggers at start time of 13:00 - with a due time of 16:00. I usually complete this before leaving work. Then at home in the evening the last one triggers the actions between 18:00 and 22:00

The above probably sounds complicated but it does work really well for my set up.

Unfortunately all of the actions and the project group will still show up in the forecast though as these are picked up by the project due date in forecast rather than the Availability filters which in the other views you can use to hide unavailable tasks
