I'm wondering if there is a way to create a custom shortcut for a Landing Page URL.
Do you mean edit the URL or use an URL shortener?
For the first one, on the landing page in the Main Marketo UI, click the "Landing Page actions -> URL Tools -> Edit URL Settings" You will also be able to create URL redirects there.
For the second, nothing is built in Marketo. You will need to use an external shortner.

I really have to show you guys Bitlify!, my little Marketo UI helper to create Bitlinks within Marketo. One of these days...
