A new Renaming options - convert spaces to underscores

" convert spaces to underscores "

would be cool, as I have to do this manually when batch tagging

I know this can be half done in the 'tag to filename' but that is only for when renaming from scratch I am seeking to just convert spaces to undercores or to any desired character while batch tagging

plz consider

You can do this either with a Replace action or with the $replace command during Tag - Filename.
