I'm working with the Translation Provider plugin API for Trados 2017. We're building a translation provider plugin which is a broker to multiple translation engines. In the "Project Settings" dialog, under "Translation Memory and Automatic Translation", there's a list of the translation providers associated with the project. When this window is open, BEFORE the user selects "OK", is there any way to access that list? It's not the list of translation providers in the TranslationProviderConfiguration for the project; if you've added or removed translation providers, the TranslationProviderConfiguration is only updated when the user selects "OK". My use case is that I'd like to modify the options for the UI dialog for our translation provider broker depending on which engines are currently selected.

Thanks in advance.
