Easy finding/filtering of Calendarific sensors in scripts/cards/etc.

[cerebrate]

I'm looking to use the Calendarific integration with a fairly large number of sensors, and would like some way to easily filter out all the Calendarific sensors for use in scripts, templates, cards, etc., such as (for example) https://github.com/thomasloven/lovelace-auto-entities .

Would it be possible to have this integration mark all its created sensors as belonging to a single "Calendarific" device, or even place them in a common area, to provide an easy way to identify them collectively?
