Would it be possible to add a way to upload teaching collections via CSV files (the way you upload to custom collections). As of now you have to either search and select sentences from existing collections (and the custom collections that I have added does not show up in this search), or you have to type out the sentences one by one.
I have a collection of CSV files with ready-made sentences for my students. It seems like a lot of work to type them out manually.
If custom collections that I have added myself would be included in the search for sentences to add to the teaching collection, that would also be an alternative that is better than typing.
