accomplish button carriage code copy define doesn entered exact flash function help individual issue mac manually page price products recognize return sku stock variants weight written

I have about 50+ products that use the exact same variants code. Currently if I make a change, I have to go in to EACH of the 50+ products and change the Variants. Nothing else needs to change in the button code other than what is entered in the "DEFINE VARIANTS HAVING INDIVIDUAL PRICE/WEIGHT/STOCK.SKU" page.

Is there a way to do one change that gets written to each of the 50+ products? It also takes more time since the copy and paste function in Mac doesn't recognize the carriage return, which I understand is a Flash issue.

Thanks for any help.

The only way to accomplish this is to manually change each one
