Audio transcript over several audio channels

I have a small problem with the new "Text to Speech" module. In and of itself, it works much better than expected. But at one point there are problems. I wanted to apply the module to a longer conversation between four people. Before, I had already separated the audio tracks and created a separate audio track for each participant in the conversation, which only contains what the respective person is saying. I thought it would be easier for this new feature to distinguish between the people. But unfortunately there is no option to create a transcript over several tracks at the same time and to distinguish the persons on the basis of these. I tried a workaround in which I tried to recognise the tracks one by one and then merge them. This did not work well either. Because it simply placed the text of a new track under the existing one in the transcript. This made the transcript messy. Furthermore, I would like to know if this feature is also planned in Audition? I would like to use it for my podcast productions directly in this programme.
