Here is my setup so far:

```auto
┌───────────┐ ┌───────────┐
│SOURCE 360p│ │SOURCE 720p│
└───────────┘ └───────────┘
┌─────────────────────────┐
│ MEDIASOUP │
│ router ────► consumer │
└───────────────────┼─────┘
              WebRTC│
                ┌───▼────┐
                │ CLIENT │
                └────────┘

```

Both sources are two different resolutions of the same stream. I want them to be delivered to the consumer/client as simulcast.

The question is, can I use two RTP producers (one for each source) and combine them within mediasoup to one simulcast consumer? I am fine if the answer is a simple no, then I will do this outside of mediasoup. I just would like to do as much as possible inside mediasoup.

[Edit: Moved to mediasoup-libraries category since I only ask about the mediasoup API side of things. I am not asking for solutions outside of mediasoup as those would be outside the scope of thi whole forum anyway]
