Hi! 

I'm making a site and this plugin is the main feature, is a pricing website where we search prices of similar products and then compare it with ours to adapt de price, so I'm making a table of products with all of the info of each product, so then have a table for example of this month products with a foreign key feature and add a row of the product by selecting or filters, so my question is If it is posible to autofill the others columns of that product because some columns of the month table would be the same as ones in the product table.

If not what's your recommendation for this case and doesn't repeat information every month, because every month will be very large tables, like 15k - 20k rows.

Any suggestions? 

Thanks in advanced.

have a nice day.
