Looking for the following Translation Memory settings in the API: Alphanumeric Strings and Acronyms

Hello team,

I'm creating a plugin that will enable or disable all the automatic substitution settings in a project. 

I have so far identified the correct properties for Dates, Times, Numbers, Measurements and Variables. However, I cannot find where "Alphanumeric Strings" and "Acronyms" are exposed in the API.

ISettingsBundle settings = project.GetSettings(lang);
TranslationMemorySettings tmSettings = settings.GetSettingsGroup<TranslationMemorySettings>();

tmSettings.DatesAutoLocalizationEnabled.Value = !tmSettings.DatesAutoLocalizationEnabled.Value;
tmSettings.TimesAutoLocalizationEnabled.Value = !tmSettings.TimesAutoLocalizationEnabled.Value;
tmSettings.NumbersAutoLocalizationEnabled.Value = !tmSettings.NumbersAutoLocalizationEnabled.Value;
tmSettings.MeasurementsAutoLocalizationEnabled.Value = !tmSettings.MeasurementsAutoLocalizationEnabled.Value;
tmSettings.VariablesAutoLocalizationEnabled.Value = !tmSettings.VariablesAutoLocalizationEnabled.Value;

Would you be able to tell me where I can find them?

Thanks!
