IOS installs storyboard layout as rtl

I have built a storyboard as an RTL layout for viewing in one language (Hebrew),

Now I need to add an English option, but the auto-off is mirroring in the opposite direction, as originally the LTR storyboard.

In sum, I have RTL on an LTR storyboard and I cannot find a way to change the storyboard setting from default LTR to RTL so that auto mirroring matches the languages.

The language in my info.plist is set to "he", I have edited the project files so the development language is Hebrew,

Is there a way to fix the situation without restoring the entire history?

Thank,
