Zoom meetings - spotlighting and screen share

[SeanRapson93]

Hello

I am running large Zoom meetings of 200-300 participants. We have a speaker on screen who shares her screen whilst teaching the class.

Unfortunately, the speaker is very small on the side of the screen. We spotlight her to ensure she stays visible but would really like to make her bigger.

Is there an option to make the spotlighted speaker appear almost side by side to the screen share? Or at the minimum, increase the size of the speakers tile?

Thanks 

Sean
