Profile Workflows - have to update same drop down 4 times. Another way?

I have 2 profiles types in Easy Social (Basic & Premium member)
I created 2 workflows (Basic & Premium) as they have different access control lists
A member gets Basic by default and pays a subscription to get Premium ACL
The workflows are identical as are the fields and values inside each

I have a drop down list in Basic and Premium workflows called "Current Industry" which has a standard list of industries. It is the same values for Basic and Premium.

I also created the list in a section called "Capabilities & Experience", it is in both workflows and has the same values.

So there are 4 instances of the same list of values.

This seems v inefficient as every time I update it I have to do 4 times. I would think you create somewhere once and use in both member types.

There is no bulk upload values option so I have to update the 4 lists 1 by 1 value.

How I can make this more efficient? e.g. Update the dropdown list once and then use in multiple places or bulk upload a list 4 times.
