It would be a very interesting, practical, and useful feature for any company that needs to filter and automate their milestones more efficiently.

would the ability to make this part of the automation process for higher efficiency

This would be of a great help to us as we are looking to shout out invoice emails once mile stones are done using automation, would love it if you are able to incorporate it

+1 Would love to see this - Currently wanting to use this in an automation where depending on a certain trigger to mark the task as a Milestone!

Would like to be able to set an automation condition based on specifically MILESTONES. My use case is, if a due date changes, I want to be notified somehow. Given current options, I guess I'll have to create a separate list for that..

+1. I'd love to be able to automatically turn a task into a milestone as part of an automation.

Yes, I would like to be able to change a custom field value once the a start date or due date of a milestone occurs

Yes. I strongly support this request. One of the automations that we have is an automatic assignment once it is moved to the folder but I would like to filter out milestones. We use this in the Gant Chart view where we break up departments into lists and use the list color to view colors on the gant chart.

This would be super helpful. We would like to auto populate milestone dates based on project end date. (Ie allow 3 days for X, 5 days for Y etc)

I have a custom dropdown field to define the "type" of activity, and when this custom field is either set to "Delivrable" or "Milestone" or "Invoice" I would like to automatically mark this activity as a Milestone.
