Link data from supplier to product

i had linked supplier to products by adding a table for items in supplier doctype .It is showing . the same i want it to link to item doctype to link to supplier automatically . can this be done ?

Check “Supplier Details” section in Item, maybe it already has what you are looking for

I create products only once , suppliers database is big and they can be added regularly . its easier for me to add the items there in supplier page .

Also i check out the feature you have send screenshot of . but i have to manually go there and add suppliers everytime . its better if both are linked and can be added from any doctype, item or supplier .

but the same is not reflected in the products page , how do i do that .
