Default PL Mount and data connection

In order to align the data connections on my Arri Ultra Primes the lens mounts with the focus scale facing up rather than toward the operator as it should (see attached image).

When the new PL mount is installed is it possible to re-align the data connection so the lenses will mount with the correct orientation toward the operator?

One more question- Is the data connection actually capturing data in the current release?

I don't see any lens information in the metadata.

Most PL mounts have a slot in each of the four ears which allow four different mounting configurations. 90 degrees apart.

This is about the data connection, not the PL slots. Yes I can rotate the lens to the correct position in the PL mount, but if I do the Data connection on my lens does not mate the camera body.

EDIT:
I attached two more photos to better illustrate what I am asking for;
1. This is the correct orientation of the lens on the body (obviously "correct" is subjective, but it is the typical position so the operator can see the focus scale)

2. If the lens is in the position shown in the first image the data contacts are not aligned as shown in the second image.

How it is with ARRI, Moviecam, Sony, Viper... cameras?

How it is with Cooke lenses and Angenieux Lenses?

Also with RED lenses?

Ok, did a bit more research and this is what I learned;

The Red lenses and Cooke S4i lenses have the data port dead center of the two focus scales which is why Red has the port at this position. Arri LDS lenses have the port above one of the focus scales and on the Arri camera bodies they have two data connections 90 degrees apart so you can put the lens in either position.

So the data port is in the correct place if you have Cooke or Red lenses...If you have Arri LDS you are SOL...unless Red decides to add a second connection similar to Arri.

Sorry about that. I see what your talking about now. I'm not fimiliar with those lenses but most PL mounts have a slot on the lens side seating surface that mates to a pin or such on the lens itself. This keeps the mount from rotating on the lens. If these are your personal lenses perhaps you could have an additional slot cut on the back of the PL mount to align right on the RED camera.
