Edit Expression editor Snippets

I would like to be able to create and edit Snippets that can be used in Expression Editor
There are some default ones but I would like to add custom ones.

For example, I really often use LINQ statements and I would like to add it to Expression Editor Snippets

Datatable.AsEnumerable.Where(Function (y) Not y("IfExist").ToString.ToLower.Equals("yes")).Select(Function(x) x("Id").ToString).ToList

Thank you

Thanks for your feedback. Added this to our requests backlog to be considered for the future.
