Yes, as long as you are using 4.5. Save as a character preset and then go to the folder you saved to, in the Content Library pane under DAZ Studio Formats, then right-click on the pane’s tab and select Create Poser Companion Files - the options under Source should be right, under Destination make sure you pick the Poser library you want to use, and the desired folder inside it and if you don’t use the CMS change the Use metadata option to Use this library and file extension, setting it to the Figure library (Cr2). That should do the job.
