Option to disable auto rendering of subprojects

REAPER is smart to always have subprojects updated. It will auto open the subprojects and render them if it detects it needs updating. This could work well for small subprojects, but I'm using subprojects to arrange a master project of big full songs subprojects that take time to render. Sometimes I am working and I don't want to render all subprojects now, but leave it for later.

When does REAPER do auto render? I've detected at least two situations:
- When opening a project
- When you switch to another application and switch back to REAPER

FR: Option to disable automatic opening and rendering of subprojects.
and
Add action to update all needed subprojects in project manually when needed

Thanks!
