[Status: Not Planned] Cascade Custom Field "Value" from Folders/Projects to Sub Projects/Folders/Tasks
If we had a custom field that would cascade down it's VALUE to child tasks/sub-folders/projects, that would solve a few key challenges we run into.
Perhaps it's adding a Boolean setting called "cascade value" and then which items it cascades to is dependent upon what's been determined in the "Apply to:" section, just below that.
Here's a screenshot of the settings idea.

I've been looking for a way to do this as well. It would be extremely useful for our organization to have this option so that we can assign different parts of a project to their appropriate teams based on information that we receive from our intake form, but at this time the information only applies to the main task and doesn't get communicated through to any of the subtasks. Having to manually copy the fields into their appropriate subtasks for each request we receive would be tedious and introduce unnecessary possibilities for error.
I'm disappointed to see that this basic feature has been requested multiple times going all the way back to 2018 and still has not been implemented. There's another request for the same feature, also submitted in 2018, currently at 140 upvotes, with a status of "backburner" here: Data entered into custom fields rolls down to subtasks
I've also found several other examples of users requesting this over the years. At least one of these has also met the 60 upvote threshold, and others are getting close to it. This is obviously a highly wanted feature. It's a shame that it's either been on the backburner for 7+ years or isn't planned at all, depending on which feature request status is correct.
