Copy, Paste and Delete User-defined Cells
You can copy user-defined cells from one shape (or master) to another or to a page.
Once a set of user-defined cells has been copied they can be used to paste many times to as many shapes or pages as you want.
The cells are not stored in the regular copy/paste buffer so you can use the standard copy and paste operations without overwriting any stored user-defined cells.
This utility can also be used to delete all the user-defined cells for any number of shapes on a page.
