Using AOI Name inside AOI as a string

Hi,

Say I have a custom AOI with the tag 'CV323' and it is declared as my custom datatype.

Is it possible to use that tag as a String inside my AOI so I can make concatenations like 'CV323 ON' and 'CV323 OFF' that are available to an HMI? I know I can declare a string with a near similar name as an in/out and type it in but would prefer just to use the AOI name.

Thanks in advance.
