Charms unable to request to be polled again soon

Bug Description

I have a charm that is blocked on startup by a resource that is created by another charm:

By default, Juju will run an update-status hook every 5 minutes, which means that charm can only check for the created resources once every 5 minutes, which means users of the charm have to wait a long time for it to completely start up. I can hack around this with

    juju model-config update-status-hook-interval=30s

But this comes at the expense of CPU, as each other charm in the bundle also starts running their update status hooks more frequently. Particularly after all charms are started up, there's no reason to keep this small interval.

I would like a way as a charm author to say "I'm waiting on a resource that will be available soon, please poll me again soon".
