PURCHASE ORDER: Product SKU & COST should be pre-filled automatically as default!

[MarcoM0857]

The Products > Purchase Orders module has been a wonderful and essential implementation for the Admin, and very well done, BUT it needs a couple of basic tweaks:

1)  The "Supplier SKU" should be pre-filled automatically using the associated Product SKU. (Very annoying to retype the SKU, and if the Supplier SKU is different, then, if different, it could always be manually changed...)
.

2) The same issue applies to the COST field; it should be pre-filled with the Product's COST already on the product admin page.
.
Frankly, I do not understand why they were not implemented in the first place.
