Group By - show more than one column

[Tamras]

Is there a way to display more columns in a gallery when its grouped?
I have a nested galleries:

Gallery #1 has the following Items property:

GroupBy(
    Filter(
        Reviewers,
        Branch = Dropdown2.Selected.Name
    ),
    "MasterID",
    "selTemp_Title"
)

Gallery #2 has the following Items property:

Sort(
    Filter(
        Reviewers,
        ThisItem.MasterID = MasterID
    ),
    RouteOrder
)

I'd like to display more than 1 column in Gallery #1 but I can't figure out how. I tried using AddColumns() but cant figure out the expression. The other columns would be Title and Description.

@Anonymous Thanks for the link. I figured it out.

AddColumns(
    GroupBy(
        Filter(
            Reviewers,
            Branch = Dropdown2.Selected.Name
        ),
        "MasterID",
        "Title",
        "MasterList"
    ),
    "Title2",
    "Title"
)

 Basically, I need to add the other columns I want to include in GroupBy (i.e. "MasterID", "Title") and then add "Title" in AddColumns
