is it possible to reference .linq file in LinqPad

is it possible to call/reference functions in another query file beside MyExtensions in LinqPad?

As of May 2019 it is possible now https://www.linqpad.net/LinqReference.aspx

In LINQPad 6 and later, queries can reference other queries with the #load directive:

#load "SomeOtherQuery.linq" // The #load directive must appear be at the top of the query

Util.linq:

void Main() { }
                
void OpenWithAssociatedApp (string file)
{
    Process.Start (new ProcessStartInfo (file) { UseShellExecute = true });
}

class ConnectionStrings
{
    public static string Test = "Data Source=.;Integrated Security=true;Database=test";
}

Some other query:

#load "Util.linq"

void Main()
{
    File.WriteAllText ("foo.txt", "test");

    OpenWithAssociatedApp ("foo.txt");  // Calls OpenWithAssociatedApp in Util.linq
    ConnectionStrings.Test.Dump();      // Reads ConnectionStrings.Test in Util.linq
}
