Setting an automation condition on the "tail" asset, expecting its dependencies to implicitly follow the same

[v1gnesh]

Say I have a, b, c, d, etc. They all, in one way or another, finally lead to 'g'.
If I set an automation condition of "on weekly cron" for 'g', is there a way in which I can I can make all its deps get triggered, because it's now time for 'g' to execute?

'g' gets a tick on cron -> its immediate deps are wanted, they trigger -> their deps are wanted, they trigger

Additionally, I have a sensor on 'b', and would prefer for it to be dormant, except for when 'g''s cron gets a tick.

Is this possible today? If not, can this be made possible, i.e., set AC on "tail" asset, and make its dep chain follow it, without needing to setup AC on each asset, or set eager on all?
