Layout problems

Hello! I was testing Localization this past weeks and I found a problem for our e-learnings. 

We always adjust the design very precisely to the text lengths, such as the button width, or other text boxes. I actually thought that in the new Localization version, it was already possible to customize these text boxes or shapes with text individually for each language. But when I change something in one language, it gets changed in all languages, including the source language.

Is this something that will be fixed in the next version? After all, the timeline can already be customized individually for each language. It would be very helpful for our workflow to change the size of text boxes individually as well.
Now we have to save the translated languages as new files but then we cannot import updates that were made for the source language..
