I'd find it very useful to be able to create an event-based trigger when "Tag is added" (similar to when "Renter Agreement is Signed"). This would allow templates and notifications to be sent as soon as a tag is added.
I'd like to be able to add a tag to a booking with a trigger. E.G. tag a booking when the Rental Agreement is signed.
This way I could easily look at my upcoming booking list and see who has not yet signed the Rental Agreement.
A trigger based on a Tag is a must. It would be great to track IDs received.
For example, I tag a booking "ID Received," then I want an email to auto send notifying them their ID has been received!
There's a sort-of workaround you could do.
Create a trigger that's sent some ridiculous time before arrival, say, 300 days. Set the criteria for having that particular tag. Then, make sure to select the option for "Try to send a missed trigger up until the booking has arrived". It'll send the next morning after the tag is set.
