Hello, is it possible to do this?

I need to output a signal in 1080i and another in 1080p at the same time

I need to broadcast in interlaced (1080i) for local television. For this I use custom RTMP Server putting the IP address of the server and the key, then, in external output I select vMix video / streaming and I put frame rate PAL 50i and Output size 1920x1080. With this configuration the broadcast is correct on television. But the problem comes when at the same time I need to stream that broadcast to YouTube.
If in stream settings I choose the second tab and select youtube, the parameters are the same as those of the broadcast, so I cannot select progressive (1080p) and on youtube the signal is with little lines when there is movement.
