Bespoke Drawing Boarders

Can you create bespoke drawing boarders in Layout?
I already have the correct boarders in DWG format but is there any way you can load them into Layout templates?
When I load a paper space I would then have the option to choose the correct drawing boarder depending on the client I am working for.

Yes. You can make your own template with your own borders and title block arrangment. You can use the native drawing tools or you could insert your .dwg file with the borders you’ve drawn. I would consider that part of making a custom template. When you’ve finished making the borders and otherwise setting up your document, use Save as Template to save it for future use.

Here are examples of a few templates with borders that I have created in LayOut.
