Change name of start page index.html

[A-Bel]

For the Publish function in Framemaker, I can't find a way to change the name of index.html as I know it from Robohelp Classic. Does anyone know if and how I can set this setting via the Settings.sts file?

Alternative: I found an instruction for a subsequent change in another post. This could be an alternative way. However, it could not be applied to the HTML5 output of the publish function. It was for Robohelp output.
Who knows a way?

I don't believe that the FM Publish route to HTML5 offers that level of control like RH does, but I haven't looked at it for a long time. I suspect that you could do a "find & replace" for all instances in the output after renaming the index page, but that would be a lot of work I think to make sure you caught all the places.
