Not sure what you mean by "prompting of snippet files" ... but, you are allowed to pick and choose the snippet you would like to import into your project.
I didn't say anything about prompting snippets. I asked about "Promoting" snippets. i.e. Sending Snippets from a Development installation of Goanywhere Director to a Production installation of Goanywhere Director.
Does Director version 4.6.1 allow for promoting of "Snippet" files?
The answer I've already received from Goanywhere Support was No. You are required to manually "promote" any snippet files created.
