Change product order details

[OswaldRunner]

Hello,

PS 1.6.0.9

My customer bought a red T-shirt size M.

5 minutes after she called and wanted to change to a blue size L, and since that combination too is in stock, no problem to accept.

 

How do I change the order?

 

It is same product ID, same price, just different combination, so the only logical way is to change in order details and let a new mail with updated information to be sent to the customer.

On this order is also 12 other things, so it is not very easy just to make a new order.

 

Preferable I would also like to add and remove order rows (not on this specific order, but as a possibility for future orders)

 

Plz help... and if not possible within PS, maybe someone know about a module?

 

Tnx in advance

Anders
