Getting EDSM to Recognize 2 Accounts

I have two accounts and two commanders. How to I get EDSM to recognize the second account?

Here are the details. I have an original account on Steam; and that was my main account for years. I first linked EDSM to this account, using the Frontier account that was linked to the Steam installation.

I have a second account through Epic, with a second commander successfully linked to Frontier through Epic. For the life of me, I can't figure out how to EDSM to read data from that second account. Every time I try, it just shunts back to the original account.

Maybe it can't be done. And if so, no worries. But I thought I would at least ask.
