Replace variable within template with TBS function

Hi people, is there a way to replace an easy variable in an template with a TBS function? my problem is the following:

i got an index.html template file in which different dynamic subtemplates should be included. at the moment i use tags like [onload;script=sources/header.php;subtpl] to load the header subtemplate into my index file.

but what i want is an easy and short tag like [var.header], so the webdesigners didnt get confused. it also makes things easier when working with a WYSIWYG editor to change the template design, caus a lot of those long tags distorts the whole layout.

so is there a way to replace a simple TBS variable within a template with the script load function?

I do a preg_replace to replace SSI with [onload], so that our designer can use SSI in dreamweaver.
Our dreamweaver MX 2004 does not support SSI in parent hierachy (no .../whatever.html), however when they're in same folder it works perfectly.  Or so I think, I didn't hear complains.

When you need to include PHP script instead of HTML template, you can do it with normal field:

(The section is at end of manual which may take some time to load)

thx sheepy, but this did not solve my problem. i already know how to run a script as subtemplate, thats not it. and when i use ur first answer i also got the same problem, just the syntax changes. i dont want any parameters or a file name within my html template, just a simple variable like [var.header] or even better [header] which will be replaced at run time with the script load function. thx anyways ... any other solutions?

Well, removing the filename can be easily done, if you want no parameter as well then you need some undocumented feature:

HTML
