Transheader / Transfooter in Word Layout (NAV 2016 CU4)

Hello everyone

I'm in the middle of a project that includes converting RDLC to Word reports.
So far, everything worked like a charm.

However, we've now encountered an issue: there seems to be no native way of doing transfooters and transheaders except for counting the number of lines that word will probably insert on the page before breaking...

Now, we thought: why not create a visual basic code that sums before each page break a specified range in a table (like a conditional {SUM(ABOVE)} ) and inserts the value in a field control?

Does anyone have an idea how to realize such a task?

Thanks in advance and have a great weekend!

Best regards,
Sébastien
