Separate Video Standard for Switcher and Multiview

I am in the middle of upgrading my church's livestream equipment from the ATEM Television Studio HD to the ATEM SDI Extreme ISO. On the Television Studio, in the ATEM Software Control, I am able to set a separate video standard for the Switcher and the Multiview as shown in the image below. The video standard for the switcher is set to 1080p29.97 and the standard for Multiview is set to 1080i59.94.

On the ATEM SDI Extreme ISO, the option to set the Multiview video standard is greyed out and can only change when I change the video standard for the Switcher as shown in the image below.

Why does this matter?
Two reasons:
1) We use a streaming service called Subsplash to broadcast our livestream to Facebook and our website. The streaming service can only accept the following framerates: 23.976, 24, 25, 29.97, or 30.
2) We are using the Multiview feature from the ATEM SDI Extreme with a monitor that is using a HDMI connection. The Blackmagic SDI/HDMI 3G converter is being used to convert the SDI Out from the switcher to HDMI that goes to the monitor. The monitor can only accept 50 or 60 framerate and if I set the switcher to 1080p30 or 1080p29.97, the Multiview feature will not show up on the monitor, but I will see a message on the monitor that says "Input not supported". The only way Multiview appears on the monitor is by setting the switcher standard to 1080p50 or 1080p60-which automatically sets the video standard of the Multiview.
Is there a workaround to this or a setting I can tweak in some config file somewhere that will resolve this issue?
Thank you.
