Make Assembly From Assembly/Bunch Parts as one Assembly

Hi There,

I have a Master Assembly (Huge) with many Sub Assemblies. Many times a few parts are added onto the main Assembly, So now I have a Bunch of Sub-Assemblies and Mated Parts in the Master Assembly.

Is it Possible to Highlight Components and Merge/Combine Them into an Existing SubAssembly OR Highlight Parts that I want as a SubAssembly and Convert Them into a Seperate Sub Assembly Whithout Having to Create New Sub-Assemblies and Remate Everything together.

I Have the 2014 Version of SolidWorks.

Thank You Guys For Reading

As Always All the Help is Appreciated
