Modify selection color [Winforms]

Currently we've updated our product with the latest available pdftron SDK.

As we came from version 5.1 and updated to 6.6.1 many things where changed/added.

One of the things that changed is the selection color. In the image below you can see how the behaviour was in the previous version.

First we highlight a particular part (in yellow) en then the selection needs to take place above this highlighting. (Reading help feature)

As you see the selection color was dark blue with a white font color.

Now in the newest version (6.6.1). The selection color changed (see in the image below)

Is it possible to change the selection color back to the old way or change it like in WPF (Tool.cs)?
