Functions in Must_Include QlikView

[BuTbka]

Hi!
I use external qvs scripts with the same name as qvw file. Code in the qvw script:

LET vDocName = Replace(DocumentName(), '.qvw', '.qvs');
$(Must_Include=$(vDocName)); 

I can not use binary load with this code.
I need something like this 

$(Must_Include=$(Replace(DocumentName(), '.qvw', '.qvs'))); 

But this does not work.
Is there any workaround for this? Maybe exist any system variable with document name?

This might work.

$(Must_Include=$(=Replace(DocumentName(), '.qvw', '.qvs'));
