the new HDR merge is a start, but needs enhancement

I was hoping that C22 with its HDR support would allow me to eliminate Aurora2019 from my workflow, but while its a "start", it has limitations that preclude me using it.  Long time C1 user, I started bracketing shots for HDR, but recently changed to taking a single RAW file, adjusting the exposure in the RAW file to -1 0 +1, saving them as TIFFs, and then using Aurora to generate a Pseudo HDR file.  It works pretty well for me, but alas not possible with C1 v22's implementation, so I am stuck still using Aurora separately.  Please consider implementing the capability for Pseudo HDR from a single RAW file.
