Yes, it is possible to change name here, but in some other place. More
information can be found here:

Specifically:
[VS .NET]
First of all select a user name for accessing to SVN: open the
configuration
window Tools\Options\Source Control\Scc provider and specify the name in
the Login ID field.

Using the PushOK SVN Proxy from Visual Studio, we go to Source Control ->
Change Source Control

Then we select a project and click Browse.  This takes us to the "Select
SVNURL, module and local path" screen.  We are unable to change the User
name from the default value taken from Windows.

We are using domain authentication for Subversion and have a user using a
local Windows account that is different from his domain account (so domain
authentication won't work with that User name).  Is there a way to change
the User name on this screen from the default Windows user name?  If not,
is there a reason why we can't?  

Basically, we'd either like to know how to change the User name on that
screen or have that feature added to the product.  FYI, we are have 4
licensed copies of the PushOK SVN SCC Proxy and are considering buying a
few more licenses.
