Combine views for markets based on the same question ID

Notice that there are two instances of "Will Ethereum 2.0 Phase 0 launch before 2021?". They are actually the same question ID 0x44c68bc0038635feb4bf7776c24f0c71748fa4bc3a73d3f94115959469da83a1. But there are two AMMs deployed, one for USDC and one for WETH.

I think it would be really interesting, and very useful, to actually combine their view in the UI. Rather than seeing multiple instances of the same question, you would see one instance of the question with several collateral options (and potentially different odds depending on the collateral).

This will be challenging in the "markets" view, since there is limited real estate to display multiple collateral types, but we could probably compromise by showing the top 2-3 collateral types by volume in the "markets" view, and then all of them in the market details view.

Perhaps users can switch between collateral types in the market details view.

It would also be interesting to see some comparative visualization between collateral types: their relative volumes, their odds, etc.

Where this eventually leads is the ability to see how the outcome of the event impacts/is correlated to the ratio of a trading pair. So in the above example, you could infer how ETH 2 before in 2021 will impact/correlate to the price of USDC/ETH.

In my opinion, this would be an incredibly useful predictive tool.
