Milestone functionality in Lightspeed

I'd like to be able to create milestones in blueprints in Lightspeed without having to add an end date without a start date. In other words, I'd like the Convert to milestone menu option added back in.

Use case:  I'm creating a complex project blueprint with multiple milestones. I'm not ready to add dates to all the tasks and milestones just yet. While building out this blueprint, I want to mark milestones but I can't without multiple clicks (click on Dates, add an end date, make sure start date is empty, then save).

It would be much easier and less frustrating if I could just right click and convert the task to milestone in table view while I'm creating this blueprint, even if that assigns today as the milestone date (which I can change later).
