I've set up a very small, but useful, plugin for my 3.6.8, and now processing it to be a product. It needs an upload of a .js file into the clientscript folder, but it also needs to add a single line into the headinclude template (basically the <script src> tag for the new uploaded .js file).
Is there a way to append to an existing template in the product xml file and, if so, can anyone clarify the command(s)?
If not, does anyone know of a related hook that I can use, so that I can just add this tag content onto the headinclude template?
TIA
