How to specify amount in the add liquidity link with v2 API?

[klesun]

Hello, sorry if this is wrong place to post this question.
In v1 of the Custom Linking API, there was an option tokenAmount in the /add-liquidity:

https://app.uniswap.org/#/add-liquidity?ethAmount=2.34&token=0x42456D7084eacF4083f1140d3229471bbA2949A8&tokenAmount=300?use=v1

But I do not see this parameter mentioned in the v2 docs:

https://app.uniswap.org/#/add/0x6B175474E89094C44Da98b954EedeAC495271d0F-0xdAC17F958D2ee523a2206206994597C13D831ec7

Is there a way to specify this parameter in v2 url? v1 urls don't seem to work anymore sadly ;c.
