I can think of at least three possibilities.

  * If you will use the custom code routinely, create a document
    containing it and make that document your new default document
    (Document > Settings ... > Save as Document Defaults.
  * Create a document template that contains the custom code in its
    preamble. You just create an otherwise empty document with your
    preferred default settings and the custom code and save it in your
    local templates document. When you want to use the custom code,
    start your new document with File > New from Template ... and select
    the correct template.
  * Create a module (Customization manual, section 5.2.1) containing the
    custom code, store it in your local layouts folder, and then
    reconfigure LyX so that LyX can find it. Thereafter, you can add it
    to any document using Document > Settings ... > Modules.
