When you create a new project with translated SDLXLIFF files, you can choose to physically merge the added SDLXLIFF files during project creation wizard. This is being done so that In-Country-Reviewers on the client side can review a few bilingual DOCX files instead of several hundreds of bilingual DOCX files, especially for DITA documentation project. When they return bilingual DOCX files to be imported back to the merged project, we cannot seem to do anything with the merged SDLXLIFF files with ICR edits. 

We discovered, if we create another project with the merged SDLXLIFF files with ICR edits, we can generate target DITA files.

However we have no way of unmerging the merged SDLXLIFF files with ICR edits. 

We want to be able to run translation cycle in TMS, but we cannot upload the translated individual SDLXLIFF files with ICR edits to TMS.

Thanks for considering,
