Is there any way to add related products in bulk? as far as I can see, if you have some products you want to be related, you have to do them one at a time.

for example you have 4 products, A B C & D, if I want all four of them to be inter-related I have to go to the individual product page, for example product A and add products B, C & D as related, then as relating isn't reciprocal I have to edit each individual product and relate it to the other 3.

Is there an easier way to do this?
