Is ther a way to avoid re-align?

Hello everybody.

I am new to 3D Scanning and own for a week a Miraco.

When merging several scans, I align them by features. After the Preview Alignment, I take each point cloud and delete all the bad parts. In the earlier generated Preview everything looks fine. When I generate the merge it looks like it does a re-aligment and because of the missing points it does it wrong. Is there a way to skip this new realigment?

Thank you
