I wonder if this feature request is considered/part of the Roadmap for the EIR PRO extension.
It will be handy to have a source vs a destination folder to be selected when conversion occurs. In this way, when the EIR PRO scans for the images it can "put the optimized with *.webp extension to a destination folder" vs where the original ones remain in their own sub/folder. Otherwise, it looks like messy and difficult when having several images at once to do under the same folder (jpg/png + webp). Currently, when this is done, checking via hosting panel to adjust/move them manually where the images need to go.
