[Maxima] bilinear transform

I'm trying to use Maxima to aid in "digitizing" an old 4 pole LP filter by taking its s-domain transfer
function and trying to go to z-domain via bilinear transformation.
However, I'm not having to great a success with Maxima in following the steps of:
which I use to get a handle on things, mainly when it comes to dividing nominator and denominator with Q.
I've gotten to the z transfer function but when I try to multiply the expression with (1/Q) / (1/Q) I don't
get the result I want. Probably me not understanding how to use the functions.
I've read the archives and found a thread about z-transform. Has anyone made a function to aid in s- to z-domain transfer?
