The DataTableGameplayTag plugin adds the following nodes to the engine:
This node allows you to retrieve a row from a data table by specifying a gameplay tag instead of the row name. This eliminates the need to specify the gameplay tag twice in the data table.
With this node, you can obtain all tags associated with the rows in a data table. Invalid tags will be logged.
Clone or download the repository and place into the plugins folder.
I have only tested the plugin with 5.3 but should be working on 5.1.1 onwards.
