Objects in multi-timeframe projects

[roar]

A while ago I decided to stay away from drawing objects, but here I am again.

My project will have several timeframes, e.g Weekly, H4, M30.
I want my expert to draw an object to Weekly, but all the other work is done on faster timeframes - how can I set the correct chart for the drawing?

Edit: This seems to be a deep, deep rabbit hole I am getting into. I managed to find the chart ID:s, but the MT5 strategy tester draws its own chart ID:s - so I couldn't visual test my bot even if I knew the chart ID:s. I guess its better to draw the objects to a single chart and just scale them properly.

To be honest, I still don't understand what this chart id option is, or how should I work with it
