Web Core HTML Template forms?

Is there any way we can use a compiler directive to specify which file to use for the HTML file for any given unit/form that is created, so we can use a template file?

Instead of having to copy paste HTML code from each form created for the application, to each form in the application (that needs it), it would be nice to have a property or directive somewhere that we can specify which HTML file to use for that unit/form instead of having to use the default unit.html file created for each unit create and praying that the programmer remembers to copy paste the HTML code that was updated for the forms, to all the required forms that use the exact same html.

At this moment there is no such setting but this is a good & valuable suggestion.
We'll discuss this with the team and consider such feature for a future update.
