WMS rule restrictions sequence to filter lot numbers before passing to function

I need to pass sales order line IDs and lot numbers to a function in a WMS rule and the function must return a lot number to the WMS rule. There are however other rule restrictions that also apply to the lot numbers, including other functions. I the other restrictions to first filter out the lot numbers, and then only the lot numbers that validate based on the other restrictions, to be passed to this function.

Does this only require me to put this new function last in the sequence of the rules?

Example of function:

FUNCTIONA(ool.line_id, mln.lot_number)
