How do I create a pattern swatch using objects filled with a texture pattern?

I am relatively new to illustrator so bear with me.

I would like to create a repeating pattern by dragging over a design into the swatches menu. I set up my art board however some objects contain a texture pattern fill I previously created. It is my understanding that you cannot create a pattern with objects that contain a pattern. However, are there any work arounds to this? For example how do I "finalize" the object texture pattern so that they are individual editable shapes instead of simply a fill?
