illustration of alternative solution (convert subtitles to video text media FX)

Hello,
Firstly I want to quickly say that Kdenlive rocks. I used Sony Vegas for 10+ years, and feel so dumb for not discovering Kdenlive sooner. It's so much smoother and more stable to work with. I love it.

The issue: 
I am working on a long video series that constantly has 2 or more people talking. Consequently, I want to have subtitles in multiple colours, both for immersion but also so hard-of-hearing and deaf people can distinguish who is talking. It's quite common to see this in news broadcasts etc. in a public space, so I was surprised to see that Kdenlive currently only supports a single Subtitles track, and only allows for a single, global colour for the subtitles' font. 

Whilst I can use the transcription plugin to generate initial subtitles in a single colour for several people, the only solution to get more colours is to convert one of the two people *manually* as a video track text media FX. This would cumulatively add up to thousands of hours across the series, which is prohibitively time-consuming. 

The solution:
If it was possible to have multiple Subtitles tracks, I could simply set each one to a different colour, and drag the transcription-generated subtitles to the appropriately-coloured track.

Alternative solution:
If it was possible to click and drag subtitles onto a video track (i.e. converting them into a 100% identical video text media FX event), this could also work. I attach an illustrated screenshot indicating what I mean.

I think both these solutions are worth adding as they shouldn't be too difficult, and would make the program that much more powerful for people who work with complex subtitles a lot. 

Thank you very much for your time and consideration!
