You would have to create a custom procedure to do this. First, remove the nether-type portal in your dimension element (there should be a check box for no portal)
Next, you would need to create your portal frame block & procedure. The procedure would have to check for the portal shape (which can become a bit complex, checking for every possible shape). You will then have to create an "igniter" (like flint and steel) so that you can light up your portal. Then set up a portal block. Make it so you can walk through it, and so it is unbreakable. Then set up a "when entity collides in block" trigger, and make a procedure that transfers you to your desired dimension.

Ok thanks I'll try that
How do you make the portal block teleport you to the other dimension?
