The second method is only slightly modified in the first method. When determining the cell, a condition column is added:

If (gvr. cells [cellnum]. Text + gvr. cells [cellnum2]. Text = gvrnext. cells [cellnum]. Text + gvrnext. cells [cellnum2]. text ). Of course, the second method can be extended and merged based on the conditions of multiple columns.
