Alert w/ Dynamic Instance Name

I have an instance spawned daily that includes the current date in its instance name (e.g. “instance-YYYY-MM-DD-name”) to differentiate it from the instances that were created on previous dates. It spins up each day at the same time and persists for a few days before being deprecated.

I need to set up an alert that target’s the current day’s instance. Is there a way to include a dynamic component in the instance name that would insert the current date?
