Merge Existing Data - Merging cells with formulas instead of merging the cells with a value

Hi,

I'm setting up a document merge in "writer" with existing data from "sheet".
The sheet is full of formulas to populate the cells for automation purposes.
The problem is Zoho Writer doesn't make a difference between a cell with a formula without a value and a cell with a value. 

Is it possible to merge only a selection fom the database? With a filter?
Something like: Merge IF cells from column 'status' are set to "to print".

Thanks,
