Orthorectification or calibration of satellite imagery, but not both?

I have some level 1b ("uncorrected", DN's) Worldview 2 satellite imagery. To make this imagery useable, I would like to orthorectify it and correct it to top of atmosphere reflectance. My image files contain an .rpc file for orthorectification, and I can successfully orthorectify the image with my DEM. However, the resulting image no longer has sensor data to serve as inputs for calculating apparent reflectance. 

Similarly, I can use the data in the .imd file to calculate apparent reflectance, but once I do so, I cannot use this file as an input in the "create ortho corrected raster dataset," as it will not accept that file as an input (maybe it is no longer associated with the .rpc data?) Does anyone know the correct order of operations to produce a top of atmosphere reflectance orthorectified image? This seems like it should be very doable! I am using ArcGIS pro 2.6.3
