AOI - change Local tag to Parameter?

Hi guys; I have a large AOI which was created with some Local Tags (UDT Structured) which should have been InOut Parameters. There are lots of references in the AOI to this Local Tag element. Is there a way to change this tag from Local to Parameter? Cannot simply create an Alias Parameter, as the Local tag is a UDT structure.

Found it! On the Add-On Instruction from the Assets tree, open the Parameters and Local Tags dialog, and in the Usage column you can pull-down to change Local to InOut Parameter, etc.
