In point editor, I would like to see a simplification tool. We make precise models but then need to export these to 3D pdf's. It would be great to simplify them (reduce number of polygons) so we can export a 3D pdf that is manageable without having to go to an external editor. This would also allow us to keep our materials. Would save time for those looking to reduce file sizes. 
Reducing by percentage would be best..
Use Save+ as you work.. allows you to step back to previous versions..Keeps a tracking history.. then go back and delete later..
Simple answer, select the meshes you want combined and right click then select merge..
They will combine into a single model.. but removes any editing.
Just a note.. ALWAYS SAVE YOUR MODEL BEFORE YOU ADD INTERIOR AS A BACKUP FILE.. more than a few times I have needed this and need to rebuild a model. Now I have the backup.
Are you trying to create an emboss on the bottle itself or on the label.. Its easiest to do on a label but you can also add a bump displacement on the bottle before you add an interior.. You might need to merge the model to do this tho.
Hope this answers your question.
We are using the Distributed with Nvidia 1080ti.. our times went from 45 minutes to about 4-5 minutes per render. That's a 10X speed improvement. Its costly but well worth it.
Best way to determine front or Bi directional is to try each..
Each gives a different originating point of distortion... Using Front will show distortions more on lets say a bottle when you rotate it to the sides. and Bi will usually give you a cleaner distortion when rotating around a pack.
Really depends on the model to which is used. I find flatter surfaces tend to prefer Front. wrapped around is Bi.
The slider 1-100 is a tough one.. in my opinion if you are finding you need anything Lower than 100, then maybe your shrink percentages are off.. Mostly this would be your tension bias. play around with this to find a "sweet" spot that gives you what you want..
Its mostly trial and error.
