Currently, to create a party with specific parameters, we have to adjust every non default parameter, which can be tedious when you organise a tourney with a lot of people and several gamemodes.

There could be a button to share the parameters of the current party as a link that could look like https://www.geoguessr.com/party?game-type=duels&mapSlug=652ba0d9002aa0d36f996153&roundWinMultiplierIncrement=3

Then, if you host a party and use this link, it would apply these parameters over the default one.

And if you are a guest in a party, using this link could check if these parameters are applied.
