I get away with only one profile for 3 cameras, main, guide, and PoleMaster (auxiliary device). The main and guide (through OAG) cameras use the main telescope info (f.l. and aperture), and I have set the guide telescope info with the PoleMaster lens specs. So, when I perform the PA, I specify the PoleMaster as the camera to use, and the 'guide' scope, as the optics to use.

When the PA is done, I revert back to main camera and guide camera, through 'main' scope.

Works nicely.

In your situation, your ASI178 could be the auxiliary camera and the 50mm lens, your 'guider' optics.

Hope this helps.
