My approach, you might consider.
I use placeholders, no need for TVs if you already have content preset (constants, no variables
)
In your template
[[*content]]
[[+formsPlaceHolder]]
In your various pages
[[$myawesomeForms:toPlaceholder=`formsPlaceHolder`]]
This is how I would test this method on one page
header ipsum----
<br><br><p>[[+formsPlaceHolder]]</p><br><br>
footer ipsum----
[[$myawesomeForms:toPlaceholder=`formsPlaceHolder`]]
And yes, you can reuse that template however you like.
If no page supplies content for that placeholder, well, the placeholder will remain nice and empty and unobstructive.
