Publishing with HTML5 Canvas: ActionScript that will directly change the HTML file.

Hi all, this is more of a general query/curiosity with regards to publishing HTML5 Canvas animations via Animate.

I'm wondering if anyone else has come across this potential 'pain point' or situation.

For context, I work with a number of design agencies which require a large number of animated HTML Banners to be exported at various sizes as well as creative/copy variations. I can be exporting anywhere up to 20-30 banners depending on the campaign specs.

The HTML5 Canvas in Animate is great for what I need but one minor downside is that I'm having to manually add both the ClickTag, Meta Size Tag and JS reference/anchor tag manually in each HTML file as per Google Ad Manager specs: https://support.google.com/admanager/answer/7046799?hl=en

It would be great if there was a way to automate the process through some form of action scripting so that each individual HTML file is directly altered to include those areas of code without having to manually go through each one.

A side-by-side comparison for reference (highlighted sections indicate added ClickTag code):

Would anyone know of a viable solution to this or are there any add-ons/extensions that would assist with this process?

Thanks for your help.
