ETH Staking / Custom token support

I staked some of my ETH in a decentralized pool (Stakewise.io) which sent me tokens as part of the contract (sETH2). When rewards are sent, they will be sent in the form of another token (rETH2).

I was able to add sETH2 as a custom currency, but only with a static value. Even so, the sETH2 value does not show up in the portfolio view.

I realize this is a temporary situation until ETH2 fully launches, but in the meantime what is the best way to track this staked ETH and the rewards I will start receiving? Would it be possible to include support for custom tokens with their value pegged to another currency? (e.g. sETH2 → ETH)
