Merge Mining Litecoin and Dogecoin (Solo Mining)

I am mining solo and I’m looking into merge mining Dogecoin.

I can’t seem to figure out how to do this. I am using a Nodejs based statrum server which claims to support merge mining.

My issue is, I can’t seem to figure out where to put in my payout address.

It was very obvious where to put my address when I was just mining Litecoin. Here. But I’m not sure how to setup to mine and get a payout for both LTC and DOGE.

Anyone out there have any experience with solo mining LTC and merge mining DOGE? Or merge mining anything?

Most instructions just talk about merge mining by joining a pool that does merge mining.
