How do I auto fill the Input Table records for batch processing the Delete Field Tool, in ArcMap?

I have over 500 individual shapefiles that need to have a specific field removed from their tables. In theory I can use the batch option with the Delete Field tool, but adding the Input Table cell for 500+ records is extraordinarily tedious. Is there some way to automate or semi-automate that part of the process? It hardly makes the batch aspect worth it as it seems to work right now.
