support for testnets / other chains ?

RLC token has "official" ERC20 deployed on Kovan/Rinkeby/Ropsten, is it possible to add them to Metamask (to make the "add token" working for testnet as well) ?

I can see the RLC ERC20 Mainnet contract address in this file: https://github.com/MetaMask/eth-contract-metadata/blob/master/contract-map.json, is it possible to add address for other chains ?

Many thanks

Start by inspecting contract-map.json, which the issue identifies as the location of the RLC Mainnet contract address. Check how contract entries are represented and whether testnet or other-chain addresses can fit that structure; the work is done when the requested RLC testnet addresses are supported by the add-token flow.
