Some values will only be known at run-time. Is it possible to use variables as query parameters in KoolReports? For example, in this example, how can I replace the raw value with a variable viz:

$val = 1.0825;
DB::table('orders')->selectRaw('price * ? as price_with_tax', [$val])

Or here,

<?php
use \koolreport\processes\Filter;
$val = 50;

class MyReport extends \koolreport\KoolReport
{
    public function setup()
    {
        ...
        ->pipe(new Filter(array(
            array("region","=","asia"),
            array("customerAge",">",$val)
        )))
        ...
    }
}

This doesn't seem to be possible and causing the challenge I have here. Or is there some other way to achieve this generally with the package?

Beginning to feel buyer's remorse...
