Edit Project template for merge segments and source editing for Packages

Hello

A template was created by a consultant for us that we use consistently when creating Packages.  However, it was noticed that the option to merge segments and/or source editing was not added into the template.

We are aware that these two options can be activated when loading up the project package, but it would be nice to have this already activated in the template.

Is there a way of editing a project template to add these two options? Or, do I have to start from another project and create a whole new template via the Create Project Template option?

Oh, on a side note.  We would like to add to the template the Google Translation API but only for a select number of translators.  Is there a way to include this API for some and exclude others from using it in one template?  Long shot question.

Thanks
