Want to set RG tags but NOT convert files

[paulr]

Hi all. I have a library of FLAC files which currently don't have any RG tags applied. I'd like to run 'batch conversion' to apply the relevant DSP settings. I'm ok with that.
However, I dont want to covert any of the files, I simply want to analyse the volume and add the RG tags.
1, is this possible?
2, if so, how?
Any tips/info appreciated.

Use batch Converter, select the whole library (first folder) >> Convert

Choose the encoder as [ReplayGain]
