2 Tuya User ID's

I have a light and a switch. . . One is Tuya Smart and the other is Smart Life. Same email as login but has 2 different User ID. How can I add the 2nd device and HA not replace the first Tuya integration with the 2nd?

Why not put the both on the same app ?

thats not how Tuya has it set up. . . both devices are from 3rd party manufacturers and i just followed their instructions on set up. I did actually try that and the apps wouldnt recognize the other device.
