Creating a custom in-text citation style = Author, Year

I use in-text citations in word and regularly need to switch between styles depending on context. I use the drop-down list to switch between Author year, Author (year), exclude Author etc
However, I would like to add one to this list so I can use Author, year (ie include the comma). In my field I use both with and without the comma in the same document depending on context.
Is this possible? Endnote X7 (yes, I know…)
I use a workaround by manually typing Author, then inserting citation with Author excluded, but wondered if I could make it easier.

what you see is what you get. If you don’t use Author (Year) I think you can modify it, but your work around is probably the only work around, even in more recent versions of Endnote…
