Save alignment data when exporting masks to combine a top and bottom set?

Well I tried this on the first side…

  • import side 1 set of images, align, create model and export masks

since the table was involved, it recreated the object no problem, and i exported the masks

  • open new project, import masked images from side 1, align and export component

with the table gone, i tried to align images but it now broke up the reconstruction into 3 components that i have to use control points to piece together

this is my point, is there a way for the “alignment” data from the first step to carry over to the second step?
