Have custom options and databound items in html select

I am currently trying to have a select contain a default value in the options section, while also databinding it using a sqldatasource. I know that asp:Dropdowns have the appenddatabounditems attribute, but was curious if select controls also have something similar. Or if there is any way to do this at all.

<select id="ddlRFC" runat="server" datasourceid="dsRFC" DataTextField="ControlDescription" DataValueField="ControlValue" class="form-control">
      <option selected>Choose...</option>                                   
</select>

It doesn't. Looking at the source, any existing items are always cleared when the HtmlSelect control is data-bound:

/* Copyright (c) Microsoft Corporation.  All rights reserved. */

// create items using the datasource
if (dataSource != null) {
    ...
    Items.Clear();
