Importing .csv files for transcripts and subtitles instead of only exporting them

Hello Adobe Team,

at the moment it's only possible to export transcripts in .srt, .txt and .csv files. But I can't import csv files again after exporting them?...

I have multiple projects where I have to send the transcript to my client for an external review and changes. Exporting a txt-file is extremely complicated for my clients and a source of errors if the client doesn't stay EXACTLY in the form of the txt file. Srt-files need to be converted and are therefore also complicated. Nearly every client works with excel, so a csv file is great for them (the export of a transcript works perfect.) BUT I need the possibility to import these files again after they were revieved.

PLEASE add this feature. It makes no sense for me, why I have the ability to export a csv-file but can't import it again.
