App Swap instead of Blocking

This is from a DM:

I had noted down a feature idea that might speak to you: the “app swap”.

The idea is that during focus time, when the user tries to open an app, instead of showing them the blocking screen, we open another app of their choice instead. For example, I just subscribed to Le Point, I have the app on my phone, and I would prefer to spend time on it rather than on IG. But my autopilot kept the reflex to open IG, so I would like to be redirected to trigger a moment of consuming useful content.

Thank you for the request!
