Changing product name on existing client files

I am trying to add a hyphen to our product's name. I can do that easily through wyBuild on General Information/Product Name. If I create a new client file, it has this name with the added hyphen. This is good.

For existing versions of the product, however, if I run wyUpdate on a client machine, it will update the version number of the client file to the newer version, but the product name does not change for me; it is still missing the hyphen I added.

Can the product name be changed via wyUpdate?
