why in my wagtail-modeltranslation the EN and NL versions are completely separated and i must to rebuild again for NL version.

[Matu-sunuwawa]

When i make a new page, i need to build the content with all the blocks. Text, images, and all that. When i want to do the same for the Dutch version, i need to repeat all those steps to rebuild the page from scratch. This is a waste of time. i would like a function that allows us to copy the blocks from one language, and paste them into the section of the other language, so i only need to change the text, and not add all the images and stuff again.

but if there are best other solution am glad to hear!!!
