Miguel,
To Assist us to understand your requirements are you Looking for Margin to be set at the Folder Level or the Takeoff Level.
Yes, I add the markup last on parent object. Not sure if this is possible aready Iām familiar with Planswift.

Or at least make markup editable on table view
This feature is under active development. The team anticipates it will be available in the upcoming release or soon after, pending any unforeseen challenges.
Hey Miguel, you can now edit in the grid with our latest release š

You currently can't update the markup % for the takeoff row, but what you can do in the meantime is create a custom property at the folder level or at the takeoff level, inherit it down to the items, and make markup % reference this custom property. The custom property that you create to be set at the folder or takeoff level will be editable in the grid.
