Color profiles/color space

[PixBruno]

I typically set my cameras to use the Adobe RGB 1988 color space. I also have a huge number of TIF images that were converted from raw, and into this color space. (and are tagged with this color profile). They don't look right when opened in PI12. Is it possible to work accurately in a color space other than sRGB? There does not seem to be a way to change the "Image, graphic, or text generated by:" box in the "COLOR MANAGEMENT" dialog box. It always shows sRGB.

Is there any way to convert from one color space to another in PI12?
