Pix4DCatch: merging on "cloud"

It would be very interesting the possibility to merge different projects in one project also on “cloud”: this is possible in Pix4dmapper but not on “cloud”, if I’m not wrong. I mean that sometimes it is necessary to complete the survey scanning also the buttom ant this may be another project, like the “inside” one (if possible), isn’t it? Look at this Pix4Dcatch and iPhone 12 Pro
