How can we pass our own command runners?

[vamsidogiparthi]

I see we have this code in the UpsertCommandBuilder to build the command based on their runners. Is there any way we can pass these runners or replace them with our own IUpsertCommandRunner to actually customize few methods or add few etc on top of the existing ones?

     private IUpsertCommandRunner GetCommandRunner()
        {
            var dbProvider = _dbContext.GetService<IDatabaseProvider>();
            var commandRunner = _dbContext.GetInfrastructure().GetServices<IUpsertCommandRunner>()
                .Concat(DefaultRunners.GetRunners())
                .FirstOrDefault(r => r.Supports(dbProvider.Name));
            if (commandRunner == null)
                throw new NotSupportedException(Resources.DatabaseProviderNotSupportedYet);

            return commandRunner;
        }
