No, but when you create a profile and do a "file/save" (which updates the .mzd file that is currently open on your computer) or a "file/save as" (which creates a new .mzd file on your computer), and then at a later time you create an additional profile and do a "file/save" or "file/save as," when you "save all to DEQX" what will be uploaded to the DEQX are the four profiles that exist (or don’t exist) in the .mzd file that is currently open.
So you can create a profile, store it in a .mzd file via a "file/save" or a "file/save as," and at a later time create an additional profile in that same file, and then a "save all to DEQX" will upload both profiles to the DEQX.
