Mirroring Named Ranges

[wjcjhwk]

Forum newbie here.... for this problem I am working within one worksheet. This worksheet contains 20 different datasets which are divided into separate 30 x 10 grids, all of which help comprise a larger 300 x 20 grid. I have defined each smaller grid/dataset as its own named range. Originally the entire dataset started in A1, but I am shifting it dataset down by 40 lines to create space to work at the top of my workbook.

I am wanting to create a data validation list in A1, then have cells A3:J32 populate with the named range I select in A1. However I also want this populated dataset at the top of the sheet to be a mirror -- not a copy. Therefore once I have the data in my range available A3:J32, anything I manipulate would be mirrored in the original range in the lower portion of the workbook.

Any advice would be appreciated. Thanks for looking!
