How to input prefixes to SKU in Update Feed?

Question: 

I have to make some changes to the feeds since my current company has added vendor designations before the SKU, i.e. for Apollo, they have A-SKU. But the feeds do NOT have that designation before the SKU. They have a program that automatically looks within that vendor's files and then adds the inventory and images. Let me know how you can handle that issue.

Solution: 

Store Prefix/Postfix

When to use:

When the SKU in the store has more character than the SKU in the feed.

For example:

SKU in store = ABC1234
SKU in feed = 1234

Insert ABC as the store prefix

Feed Prefix/Postfix

When to use:

When the SKU in the feed has more character than the SKU in store. The prefix/postfix removes the extra character from the SKU in the feed.

For example:

SKU in store = 1234
SKU in feed = XYZ1234END

Feed prefix = XYZ
Feed postfix = END

Does it handle support prefixes?

Yes, the handle does support the prefixes.
