I was thinking...
Assuming your project is currently in English and need two more localizations (for example German and Spanish). You can let an AppleScript create 2 custom columns and fill them with the current content of the Title column.
The script is this here:
tell application "Merlin Project"
set rootProj to root project of first document
set theRoot to root activity of rootProj
set allActivities to child activities of root project of first document
try
get custom field value theRoot for "Title.de"
on error
-- create new custom field
make new custom field at rootProj with properties {title:"Title.de", extended class:activity}
end try
try
get custom field value theRoot for "Title.es"
on error
-- create new custom field
make new custom field at rootProj with properties {title:"Title.es", extended class:activity}
end try
repeat with act in allActivities
act
set custom field value act for "Title.de" to title of act
set custom field value act for "Title.es" to title of act
end repeat
end tell
Afterwards you enable those columns in the outline to start translation:
You use the translation feature of the macOS and correct when required.
Afterwards you can create views for the individual localization and activate only one of the tile columns.
Would that help you further?
