Linear To/From dB graph process

I’d like to use the Graph Processing Tool to transform my finished Gamma product, but also maintain my other existing bands (I’m preserving the DEM and local incidence angle as bands). Each time I use the Linear To/From dB tool (I have been applying it after Terrain Correction), it deletes all other bands.

Any ideas for a workaround?

Thanks in advance.

You can append a merge step. Use one of these operators, BandMerge, BandSelect or Merge.
