User Settings: crossDesk > Auto-Propagate
In the Auto-propagate section you can specify that Across checks whether a newly translated (or corrected) paragraph also occurs in other parts of the document. If so, Across will automatically insert the translation at those points, if the auto-propagate function is enabled. In order to avoid previous translations from being overwritten, you can specify that the auto-propagate function only works for paragraphs with the editing state "Untouched".
In addition, you can determine that the paragraphs in which the translation is inserted via the auto-propagate function are to be set to the paragraph state of the paragraph that is currently being translated.
